Hi, I have just registered on this forum tonight. I have a terrible situation in my 3ft community tank. It is well established ( about 3 months). Other than an outbreak of whitespot a month ago I have had no problems. About a week ago a small honey gourami puffed up and died in about 24hrs. I looked up dropsy but it didnt have a pine cone effect, in fact its body looked quite smooth. Yesterday morning I found my blue gourami dead at the bottom of the tank, it looked normal. I noticed that one of my clown loaches looked odd, this morning both my clown loaches were dead, one was very bloated (but not its head) the other one looked fairly normal.. During today two platys have died, they almost seemed to drop down dead, one minute they looked fine and were feeding, the next they were dead. Whatever it is it is killing my fish quickly. I cannot find a disease description that fits. Can anyone help!!!!
 
Hi,

What are your water parameters, how many fish and size of tank.

Thanks
Amy
 
youve got to test your water.... at least ammonia...it would be good if you test nitrite and nitrate
 
We need more info:

Specific size and stock
Water parameters (ammonia, nitrite, nitrate)
How you cycled
Maintenence schedule
Temp
Feeding behavior
Anything else that you might think could have contributed to the deaths...
 
also water change schedule - how much and how often?
 
Hi again, it is a 3ft tank, temp is 31'c, PH is 6.8, just done a nitrate test and it comes up yellow (this says its fine on the chart ) Tank mates are 3 glass catfish, 6 rummynose tetras, 6 cardinal tetras, a ram and four aquatic frogs, I also have two guoramis left. I feed tropical flake, algea wafers and quite alot of bloodworm ( have too so the frogs get it) I have a large fluval filter with carbon added. I do a 20% water change every week. The filter sponges get cleaned every 8 weeks in tank water.
 
Forgot to mention, the very bloated clown loach that died looked quite red around the gills.
 
redness around the gills could be ammonia/nitrite poisoning. you need those test kits. nitrates should be above 0, especially since you are only doing 20% water changes. no nitrates means that your tank is still cycling (not established), and therefore toxic to the fish.

as for the tank size, 3ft doesn't tell us much. do you know how many gallons, or could you measure the tank and tell us the dimensions of it?
 
I agree^

We need ammonia and nitrite readings as they are far more toxic than nitrate, which only is dangerous at higher levels.

Your temp is also VERY warm for the fish you have. Lower it to 77-78 F (or about 25-26 C)
