I have 2 Cory's in my 75l tank, both are very slow moving, they are hiding beneath plants and sort of floating against them. When I move the plant they swim away and start again in a different spot. Is this a sign of disease? I checked my water and everything reading 0 with a ph of 7.
Aarrgg!! I had the exsact same thing happen to me... They were sluggish and then I noticed clamped fins. One of mine died, however clean water conditions really helped with the other one. I did regular water changes. What was the results of your ammonia?
Ammonia level is also 0. 2 more have died since this morning and I have no idea what's wrong! All seem to be struggling to swim, they are floating instead. I added a fish yesterday and I'm thinking that it's brought a disease into the tank.
