js Posted June 4, 2007 Report Share Posted June 4, 2007 Hi there I have a tank which has 5 fish. My most beautiful fantail has been looking unwell for the last couple of days. Swimming on its own, fin down and today sitting around the bottom of the tank. Still eating each night though. Now I have just found it nearly dead, lying on the bottom, then floating to the top on it side. At the same time my big blackmore nymph is swimming on his side at the top of the tank. Has anyone any ideas what could be happening? So far the other 3 fish (2 fantails and one comet) all look normal and healthy. The two unwell ones don't have white spot and both of their bodies look normal and healthy. Thanks Julie Quote Link to comment Share on other sites More sharing options...
jim r Posted June 4, 2007 Report Share Posted June 4, 2007 Top priority is a water change and keep doing them regularly also need some idea of water parameters ,feeding programme,temp and anything else which you think may be usefull in finding the cause.

Caryl Posted June 4, 2007 Report Share Posted June 4, 2007 How big is the tank and what size is the fish? Do you have filtration? Do you do regular water changes? Sounds like poor water conditions. Quote Link to comment Share on other sites More sharing options...
js Posted June 11, 2007 Author Report Share Posted June 11, 2007 thanks for your replies. I think the tank is 54 litres and yes I do regular water changes, although, it might have been getting close to 4 weeks for this one. I took out both the fantail and blackmore and put them into a separate bowl. Unfortunatley the fantail died (I should have acted earlier), but after a day and a half, the blackmore turned over and started swimming around like normal again. I did a water change in the tank and have added him back. Was away for the weekend, and he was sitting back on the bottom when we got home last night. He did come up for food though, but now I notice his tail is looking shredded, so not sure if the comet started to attack him, if he wasn't well. Will do another water change tonight. Thanks for your help. Julie Quote Link to comment Share on other sites More sharing options...
js Posted June 11, 2007 Author Report Share Posted June 11, 2007 Woops, meant to say that yes, I do have filtration - stingray 15 (I think) and oxygen bubbles. Quote Link to comment Share on other sites More sharing options...
jn Posted June 11, 2007 Report Share Posted June 11, 2007 How long has the tank been setup with those fish in it? Quote Link to comment Share on other sites More sharing options...
js Posted June 11, 2007 Author Report Share Posted June 11, 2007 One fish has been there for nearly a year and the one who died, about 8 months and the others about 6 months. I have had my tank for more than a year and usually have no problems, and then out of the blue one just dies for no reason. I did wonder if it had something to do with us lighting the fire now. - perhaps dust is getting in as they have survived quite happily through the summer.

jn Posted June 11, 2007 Report Share Posted June 11, 2007 Have the fish grown much since you bought them? I've read somewhere that goldfish can require up to 30L each! Maybe they're outgrowing their tank and the 4 weeks was just too long for the them to cope between changes. Have you got any test kits? I'm betting that would tell you straight away where your problem is. (I think some shops will test water for you for a fee) Quote Link to comment Share on other sites More sharing options...
Caryl Posted June 11, 2007 Report Share Posted June 11, 2007 What size is the tank (dimensions?). 54L is not very big for goldfish as they grow and produce a lot of waste. Monthly water changes would not be enough for these fish. I suspect water quality is the problem. Quote Link to comment Share on other sites More sharing options...
heyandrea_ Posted July 7, 2007 Report Share Posted July 7, 2007 I learnt that the hard way, goldfish produce alot of waste. My first lot of goldfish died of ammonia poisoning. I dont think I did enough water changes and over fed. Always a learning curve! Quote Link to comment Share on other sites More sharing options...
