Resolved Question: The filter in my fish aquarium screeching?

so i've been told by the local fish pet shop to add this stuff that helps the ammonia and nitrates in the water and a week ago i added some and the filter got louder then it started screeching really loud so had to turn it off for a while then it was fun, and today i added some more and it wont stop screeching and i keep checking if it's stopped and it's still really loudly screeching whats wrong with it?OMG it works LOL i took the filter out n like washed it out n put it back in and now it works, cheers! more

Resolved Question: What to Put in 20 Gallon?

Lets say we have a 20 gallon (high) that has clean (water conditioner in it) water, has been cycled, has plenty hiding spots, and some drift wood. There is a very strong filter in this tank. How many fancy goldfish, ghost shrimp, rubber lip plecos, ghost catfish, and mystery snails would fit in here? Show your answer like this please! example: Fancies-1 ghost shrimp-10 RLP-1 mystery snail-2 Ghost catfish-4 P.S. I do not own an aquarium. I am thinking about getting one but this is just along the line of what I want.Ok. Rubber lip plecos only get about 5" long. Apple snails and mystery snails are differnt. Ghost shrimp are awesome cuz they look really kewl like they are made of glass or something. All of them won't get eaten if enough hiding spots are provided. Ghost catfish only get 3"-4" long and don't need much space but yes, they are schooling fish. Thanks everyone but I'm sticking to my original plan-a 20 gallon with everything in my question. more

Resolved Question: How do I use this aquarium sponge filter?

I've just bought a sponge filter to use in a small aquarium, but I'm not certain I'm using it correctly... It's identical to the one in this picture: http://shop1.actinicexpress.co.uk/shops/DiscusSouth/images/catalog/Web_101_Fish_Double_Sponge_Lge_200_pix-1.jpg There are bubbles coming out of the tube at the top, but nothing is coming out of the sponges. I thought that since the sponges are where all of the bacteria is supposed to form, surely the air would need to be going through there? Am I using it right? It's set up vertically, just as in the picture. more

Resolved Question: I have a male betta in a 5g tank and I was wondering if he can still make bubble nests with a water filter ...?

turned on all the time or not? When I rescued him from Petco he was in one of those teeny little cups and so I brought him home to his 5g. palace..lol. It has plastic aquarium plants, a tiny rock cave I made for him out of loose rocks, a heater, a water filter and a hood. It's just, when I brought him home his little cup had a bubble nest in it. I hear so many stories about how betta's need water filters and there then there are those that say they don't need the filters because they have a labyrinth so now I'm a little confused. Is the filter keeping him from making a nest? If it is will he be fine if I leave it off? more

Resolved Question: how much is 10cm thick glass for aqaurium?

this is just an estimate but the aquarium is 100 meters squared. yes it's big. how much will the glass itself cost me? (not including marine pumps, filter etc!)this is a project to a dream massive garden and i thought i would add a marine system and my teacher gave me a budget of 1 million. would this cost 100,000? more

Resolved Question: Would these air-driven filters be sufficient for a 2.5 gallon tank?

I found an old 2.5 gallon tank in my garage which I'm told may be used to house one betta (with heater, obviously). Anyhow, I'm not too keen on using the ordinary electrical pump type filter in this tank. Aside from the fact they'd create a lot of current (which bettas hate) it doesn't really fit properly with the tank setup. As I also have an air pump lying around, I was looking at the kind of filters that you drive with air. This one is my favourite, as I can see that it would certainly fit. What do you reckon? http://cgi.ebay.co.uk/Brand-New-Air-Driven-Aquarium-Box-Filter-Fish-tank-/260613601388?cmd=ViewItem&pt=UK_Pet_Supplies_Fish&hash=item3cadc7f86c Then there's this one: http://cgi.ebay.co.uk/Biochemical-Sponge-Filter-Air-Driven-Filter-/260612154459?cmd=ViewItem&pt=UK_Pet_Supplies_Fish&hash=item3cadb1e45b What do you think? Also, can you tell me if either of these filters are the sort that you'd have to replace the filter media on (as opposed to just occasionally washing it)? I'm keen to avoid those, as I doubt it's easy to get hold of around where I live. more

Resolved Question: Will my Betta fish be okay?

I've just got a blue Betta fish. I had a Betta fish when I was a kid but I don't really pay attention to it since I'm a cat lover. My mom just gave it to me because my eagerness to have a cat. I really don't know how it died but this time I won't let my Betta die after a few weeks. I know it may be hard and expensive and my parents might complain about it but it's for the sake of a fish's life. :P I'm they'll understand. This fish live in a small tank about the size from the tip of your finger till your wrist. I didn't bring too much money at that time and I'm planning to buy a new tank. A website says this fish needs a 5 gallon tank. What is it? My country doesn't use gallons. We learn British language rather than American. (gallons are american right?) I used a filtered water instead of the water that wasn't filtered. Is this safe? I don't think filtered water is safe for it because the website says they naturally don't live in filtered water. So what kind of water? And there is some Ammonia issue.. Can you explain? Also, I don't have a filtering system that most people use for many fishes in an aquarium. Mine is so small Seriously, it's the size of your palm!. I just talked to my mom going to the pet shop to buy conditioner water and a 5 gallon tank. Will I have to buy a filtering system for a 5 gallon tank or just use the conditioner water? How much conditioner should I put? One drop? One spoon? One cup? One glass? I put smooth rocks and one big rock in the tank and it's wandering around in it for something time. Like right now. It seems to like it. ^^ I gave the fish the food from the pet shop I bought. I gave him like 5 teeny tiny fod for him like 3 times today. I wonder how much they can eat a day. I think that's all I need to ask. Ah! Also, if it's too hard to answer .. Can you recommend a name for him? :D It is blue-black. It made me feel like it is very mysterious. -Lol, it's playing under the big rock- Also, I noticed it has a few red patterns. It doesn't like it when I opened the tank to give some food. So he's quite like a cat. Also, do you know it's gender?? http://2.bp.blogspot.com/_-TA-tn1Git4/TA5NcZrAY9I/AAAAAAAAAJI/1ay8ES4LBVM/s320/IMG_8350.JPG Thx. :) I really need a pro to answer all of this. xD more

Resolved Question: how can i make my fish tanks internal pump more quieter?

Hi, i have just bought a Betta 35 litre Lifespace Aquarium and when i set it up to stand for a week i noticed how noisy it is. It has got a built in trickle filter and pump. I think it is the pump making the noise because it is so powerful. Is there anyway that i can make it quieter? more

Resolved Question: Can someone offer another explanation to the death of all my fish?

Okay, I'll give as much information as I can. We decided to get some fish, we already had a tank but unfortunately we couldn't afford filters and heaters so we decided to get fresh water fish. We checked in at the aquarium what fish go well together and what don't need filters etc. So we stuck to the different breeds of goldfish. Our first fish was what I believe to be a Shubunkin, I'm not completely sure but it looks like one of them anyway. We had this a few weeks, we ate fine and everything etc, we'd also added a few plants for the fish too. We then got another one, similar in shape and size, it was more yellow than gold like normally fish with a red streak running through it. i think this was uncommon though as he was the only fish in the tank at the aquarium who had it. These two again got on fine ate fine and a couple of weeks later we got another fish. Not sure of the breed, I'm sure it was 'something orange'. It looked just like a mini orange, big round stomach, golden and with a tiny head. All the time checking we were okay to add certain fish etc. This fish got on fine with the others and we started feeding them daphina as it is a slower fish and needed a chance to get food over the other two. So we fed them is and always made sure they all got food. Weeks went by and we got our final fish we I think was a black moor, or at least again it looks just like one, we added a few more plants and thats when it started. The next day the one that looks like an orange was dead, however I noticed a weird bubble like thing around one eye and red marks. We took it to the aquarium in which they said a dead fish couldn't tell them anything, but then preceeded to say it was burnt and must be the pH levels in the water. We had been previously told this were more sensitive fish and more likely to die. So the next day we got our water tested and they said to remove so much of it every few days, add fresh to it and put in fish bacteria. We did this, two days later our first fish the Shubunkin died, about two days later, today, the black moor died too. Leaving now only the one I can't name. Now I can understand how the two more rounded fish might have died because of pH levels because they are more sensitive, however how the Shubunkin (again i think it is that) died too, as the more regular goldfish arent as sensitive and don't need as much care. I've now removed all the water from the tank, added fresh, and removed all the plants. dont know the effect that will have or if it's too late but it's better than watching another one die. The tank was not overcrowded and all fish were fine apart from the sudden marks on the orange shaped one. The deaths all started a day after added the last one and the new plants. could there possibly be another reason to their death?Okay first off. I've had many goldfish before who have never needed filters and lived for years on end. We checked with the PROFESSIONALS if there was fish we could have without filters which of course is the goldfish, they showed what we could have and what we could mix as long as we fed them Daphina. The only problem with having different shaped fish is if the other fish bite their fins etc. This was all explained and DID not happen. I don’t know the exact breeds because I wasn’t there when they were bought, I’ve done my best to look up the fish and put names to them but of course I can’t be 100% sure. My partner is also not here not to tell me what breeds they are. We also checked if the size of our tank was okay and how many we could have in it. I don’t know the exact size of that either. It’s not a huge one or not really small. It was the size that allows 4 fish.We did do our own research, my partner is the one who knows about fish rather than myself and so he dealt with them. We looked online first and then he got the fish and asked all the questions and made sure everything was okay with them. I would not buy fish if i thought they were going to die. We were going to take the rest back until we could sort something else out but unfortunately they’ve not made it, bar one. I’m not a selfish person and would certainly not give any pets i have had (and by god i’ve had a lot) a non ideal life. We looked stuff up, and did exactly what we were told, speaking to more than one professional at the place. Which is why i posted this question in the first place as i could not understand after following everything why they would die. I can add the other details when my partner gets home. more

Resolved Question: Can I convert a previous Marine Aquarium to a Freshwater Aquarium?

Resolved Question: Have I got everything I need to start my new tropical aquarium?

I've just been given an old fish tank and heater and I am starting a tropical aquarium. I have cleaned all the gravel and put that in, and I'm ready to fill it with water and then start the filter and add the appropiate chemicals. However, before I do I just wanted to check I have everything I need. Firstly, my filter is quite old and I don't seem to be able to find a replacement sponge that fits it. Can I just give it a rinse and use the old one? Secondly, what treatments do I need to add to the water to make it safe for my fish? I have bought a bottle to chorine/chloramine remover and a cleaning chemical which is supposed to degrade ammonia and nitrate which harm fish. Will this be enough? Finally, how long will it take after I've done all this for my water to be ready for the fish to inhabit? I know the tank is supposed to form bacteria before fish can live in it. How long would this take, and is there anything else I need to do? Sorry for the long winded question. I just want to make sure everything is all right for my fish when I get them. I'm quite scared that I'll do something wrong and end up killing them or something. Thanks.By the way, my tank is 45 litres (10 gallons). more

Resolved Question: Help?!? Red tailed catfish?

Right I have a 400 gallon tank with 4 fx5 filters so filtration is not an issue. In it there is an red tailed catfish at around 25" so pretty big. I was wondering how big will he get..? I know they get pretty big and I'm willing to pay a hearty amount for a custom aquarium but how big and how many gallons should i need for him when full grown? And where could I buy a big tank? Is 400 gallons big enough for him at the moment - with him being 25"?? I feed him a wide variety of foods such as bloodworms,feeders,crickets,ox heart,pellets and more is that an okay diet? Any tips would be helpful. Thanks..Yes Alec - I do have 4 fx5 filters. I'd rather have an overfiltered tank then one with low filtration. I don't really mind if you don't believe me - at least I know what I have. And they weren't 300 dollars I got them off a aquarist breeder for £650 for all 4 - plus he's a mate of mine. So to e honest I don't are about your opinion - you either answer my questions or do say anything. more

Voting Question: My tropical fish are gulping for air at the surface and breathing rapidly?

My tropical fish are gulping for air at the surface: This is a 100 gallon tropical fish aquarium. The temperate is a steady 78 degrees.I recently did a major cleaning of my fish aquarium..I did it fairly wrong (which I have since found out). I cleaned the tank+gravel completely and changed the filter. I also used all new water. Now I know about the biological filter but it is too late for that. Anyway, The other day all of the fish started hanging out at the top of the tank seemingly gulping for air. I did a ammonia test and the results indicate no danger. The filter drops water back into the aquarium at the top and there is also an air-bubbler strip thing at the bottom so I don't think lack of oxygen is the issue (?). Whenever I change a good amount of the water 20-40% and treat it with the proper stuff (stress coat/chlorine remover) the fish all seem to return to normal (although they still seem to be breathing somewhat fast) for a few hours and then go back to the surface gulping until I do another large water change. Any ideas? more

Resolved Question: Cloudy aquarium water after setup?

I have just set up my new planted tank with a sand substrate. I washed the sand thoroughly until the water run clear. I have had the tank set up for about and week and bit. I am running an Eheim Professional 3 filter with purigen in the system. The tank has always had a kind of white/grey cloudy colour to the water. I done a 50% water change yesterday and was hoping that would make a difference unfortunately it hasn't made any difference. What could be the problem?Thanks for all your advice. It is a fairly heavy planted tank I am waiting for my new CO2 regulator to arrive and then I will start adding CO2. The tank has no fish in it at the moment maybe once I start adding the CO2 I will introduce a few cardinal tetras to provide a small amount of waste or should I just add some fish food. more

Resolved Question: Please help my fish!!!?

I have 3 goldfish in a 60 liter tank. I do 25%water change weekly, I have a filter, 2 plants and have added aquarium salts, and stress zymes. I have had my water checked at a local pet store, all is fine. However: Fish 1 (Filbert) has a growth on him, unfortunately there is nothing I can do, but he is swimming fine, and eating fine, but tends to sit at the bottom a lot Fish 2 (Bernard) is having difficulty getting to the top of the tank, he seems to have a rocking motion as he swims. Could this be swim bladder? He also sits at the bottom. But he is eating fine. Fish 3 (Egbert) sits at the bottom for no apparent reason, and is swimming and eating fine. So if Bernard has got swim bladder, can I treat him in the tank he is in? It says on the bottle that it is harmful to organisms in the aquarium, but have been told by the pet store that it won't harm my other fish. I really don't know what to do. I have 3 fish that sit at the bottom of the tank, and I hate seeing them so miserable. If it's not the water then why are they all sitting on the bottom? Any suggestions would be much appreciated, as I am at a loss! Thank you in advance! more

Resolved Question: Changed some gravel to Sand, now water cloudy.?

90 Litre Aquarium. It had plant substrate base with gravel on top. I removed the top gravel, and the substrate is moved into a planting corner. I rinsed sand several times, then added it into the Aquarium. The water is murky, it's not like floating sand, just murky. The filter is off, but I turn on every 15 mins as I'm scared bacteria will die. Currently has 1 Platy and 2 baby platys. It's Aquarium Sand, not 'play sand' How long will it take to clear, is there anything I should do. CheersAccount Closed - My filter has a powerful output, should I leave it on do you think?Jim - no, it's not Biological disruption, silly! I know about Cycling and my tank has cycled, although bacteria is in the gravel; A) I havn't removed all of it and B) It's mainly housed in my large 2ft by 15cm long filter.FFAFish - thanks, that sounds like something that could work. The filter is on, I may add some Nutrafin Cycle. more

Resolved Question: Is my koi fish depressed?!?

I've had my koi fish for about a year, he's about 5 in long in a 20gal tank along with a bottom feeder whom I've had for 3 years and is also about 5 in long. I keep a variety of small and large rocks at the bottom of the tank, I use an Aqua-Tech 5-15 filter, and I add 2tsp of Jungle Start Right with Allantoin to the tank after I change the water. After the last time I cleaned the tank, he has been acting very strange. Since yesterday morning he's just been sitting in the same spot at the bottom of the tank and won't move unless someone walks by. Then he will swim around the tank like crazy for a while and then return to the same spot. Yesterday he still had a good appetite, but this morning when I fed him he didn't eat anything. I recently changed his diet to small crickets as well as bugs that I find in the yard, because I read that it's a great diet for koi. I thought maybe it would be his swim bladder but he doesn't have any problem swimming, his breathing is normal. His fins, gills, and scales all look perfectly healthy and his eyes are nice and clear. Although he has been shifting his eyes downward in a sort-of blinking fashion. So what's wrong with him? Should I buy some aquarium salt?BY THE WAY I AM NOT KEEPING THE KOI IN A TANK HIS WHOLE LIFE I AM CURRENTLY IN THE PROCESS OF DIGGING A POND IN THE BACK YARD. I STUDIED HARD BEFORE I BOUGHT MY KOI AND I AM PROUD.OK so I put them in a large pot with different water in it and after about 5 mins they started acting normal again. So its definitely something in the water. It might have been from the new rocks that I put in the tank after I changed the water because I mistakenly did not take care to wash them off turally first. AGAIN, I am building a pond for them, they have a good home, no need to worry about that. Right now the tank is a good size and only a temporary home for them while I'm getting the pond ready. I will change the water in the tank now and take out the new rocks that I put in, and as one of you said I will go and buy a better filter for the tank they are TEMPORARILY staying in. I did ALOT of research on my fish before I bought them because I had many goldfish when I was younger that died and I was sick and tired of it. So I made sure I knew alot about the fish I was buying this time. Anyways the problem is now resolved. Thanks for your comments anyways. more

When I opened the filter housing I noticed a basket containing white stones? in the lower section. Upon reading the instruction manual on the Juwel website I've discovered this is Cirax filter media which I had never heard of. Do I actually need to bother using this Cirax? My own Rio 180 doesn't have it, just fine and coarse blue sponges and I have no problems so I'm wondering whether to take this Cirax out and not bother replacing it. I've never seen it for sale locally so I would need to buy it online. more

Resolved Question: How do you clean out an aquarium?

I don't have fish, and don't plan on getting any... But, I've always wondered how people go about cleaning out a fish tank?! Surely once in a while even if you have filters etc you need to change the water in its entirety? How do you go about that, what do you do with the fish?! Sounds like a mental question but I've been wondering for a while.. Thanks! more

Resolved Question: my fish tank aquarium is always cloudy?

i have a 29 gallon tank with a blue lobster in it...i clean the water weekly, i usually have to clean over half of the water out because its always super cloudy. i have also tried cleaning only 20% of the water out at a time, and i get the same result. i syphon the bottom of the gravel as well and scrub the glass with an algae cleaner. i use tap water conditioner and also a water clarifier. my tank is not new-i've had it for about 5 months now, but the same problem all the time, i haven't added any new decorations or anything like that and instead of getting clearer over time, it gets worse and worse as time goes by...by the end of the week, you can't even see through the water...i also change the filter regularly, i've done everything instructed to me, i can't figure out what the problem is...its not the lobster itself as i've had the same problem with other fish...thanks...when i say i change my filter regularly, i do what you said-rinse weekly and change monthly...the best answer is probably the last one about the window-its not directly in front of a window, but off to the side next to it with just a little indirect light...and yes, the water does turn green after ...also, i'm not syphoning ALL the stuff at the bottom either...i just don't get this...and the gravel was rinsed before putting in the tank...i will try turning the light off during the day and sitting a bowl with tap water in it for a few days to see if its that... more

Resolved Question: Please help with my fantails?

Please help my problem with fish in my aquarium. I have a small aquarium with two fantails. About a month ago one of them started diving around the water and then floating on the surface curled around as if dead. However, every now and again he swam round normally though seemed to have difficulty breathing. (I took him out of aquarium and put him in fresh treated water). After three days I decided he'd had enough. This is now happening with the second fish, his stomach is maybe distended and the flesh near his tail fins seems withered. The water has been checked and I treat the fresh water, also the aquarium has a filter. I am thinking of giving up! Any advice would be appreciated. more

Resolved Question: Help with External filter for Tropical Freshwater aquarium?

Resolved Question: Is this a good mix for my aquarium?

Hi, I have only had my aquarium since November, and all seems to be going well. I just want to ask the experts if my mix is OK. I have 2 shubunkins, 2 red and silver goldfish, 5 zebra danios, 3 platys, 4 paradise fish and 1 sucking loach algae eater. I have a 125l tank, and there is lots of plants and plenty of space. Your comments would be appreciated. P.S. I lost one platy the other day. She had been nipped by the male, and had been hiding for a week or so beside the filter. I had been adding medicine, but I think she got too stressed. He is still chasing the females, so I was thinking of putting another 2 females in, to give a ratio of 4 females to 1 male.Sorry i meant 125 gallons. I am going to buy a bigger tank in the near future, but at the moment there is plenty of space.OK Thanks for your answers. I will decide what I am going to do. I did buy all of the fish from the same shop, and told them each time exactly what I had. They said that the platy's, danio's, loach and paradise could go in cold or warm. My tank doesn't have a heater in but the temp sits between 76-78 degrees, as the house is warm. I will sort something out. Thanks more

Voting Question: how do you use 'filter start'?

i have a new aquarium and im cycling it for 2 weeks before i get my new fish, ive put the 'tapsafe' in that i needed to use, but i also got some 'filter start' with the aquarium but i have no idea how to use it. the diagram shows the stuff being poured into the back of the filter at the top, but i cant find a hole in the top of my filter for the stuff to go. ive tried reading the instructions but they dont help, and it doesnt even tell you how much i should use. and one other thing, the water is slightly cloudy, is this normal http://www.webbsdirect.co.uk/images/products/medium/322552.jpg thats the stuff ive gotmy tank is 64 litres, and ive read i have to put it in when i get my new fish. more

Resolved Question: Will her fins grow back ?

I recently thought one of my platys was pregnant as she had been hovering between the filter and the back of the aquarium, then moved down and seemed to hide nearer the bottom of the tank. She was also getting fatter. I have been keeping an eye on her, and noticed tonight that her tail fin has been nibbled. On closer inspection, her left fin at the front is tiny, and looks as though it may have been nibbled as well. She seems to be avoiding the other fish, and just staying low. She does still look fatter than she was. Is it common for them to be (attacked) as such when they are pregnant and will her fins grow back. What should I do for her sake ? Any answers will be much appreciated. more

Resolved Question: What happened to my neon fish? They're dead?

I had 10 neon fish. Two days ago there were only 9. yesterday only 8 and today only 6. I bought them the 31st of december 2009. I also have 1 pleco 1 male betta splendens 2 aquarium frogs 5 synodontis? i dont really know what they're called 10 neon fish yesterday we couldnt find the missing two neons... and we thought one of the frogs might have eaten it. (it was kind of fatter). And i saw the frog going towards the filter and scratching something from there, and the other 8 neon were getting very close to the filter and we didnt know why. So i checked, and i saw this fleshy tiny thing stuck between the filter and the glass, and i realized it was a neon. so i was like freaking out cos it was squeezed and its eyes were like popping... so i quickly removed the filter, and opened it up. and there it was, my tiny little neon, dead. so i cleaned the filter, and i kept my neon in a little plastic box, wrapped in a tissue. And this morning there were only 7 left- and i was looking at my aquarium and i saw this little neon it was 'stuck' to the glass, i mean it didnt move... so my mom banged on the glass and it moved away, but it was very very weak, and it kept on going down and couldnt swim up, and then the frog was biting its tail, but the neon swam away quickly, and joined the other 6 neons, and then my fighting fish 'bit' it, like pushed it away with its mouth. Then it was so weak that the filter sucked it. And we could see how this other neon was following it very quickly as if to try and help it but it died and i couldnt see it anymore, so i guess the filter sucked it. Its so sad and i dont know what to do with them. i dont want the rest to die and im still missing 2... cos i dont know where they went... maybe they're in the filter, or maybe the frogs ate them... Im gonna bring them to the fishstore tomorrow. :( Someone help? whats wrong? more
