Question

the tank and water is fine ive checked all the levels and the amonia and nitrite are fine i didnt see the barb die but the guoarmi ive been watching for a couple of hours and he was behaveing wierd just sort of floating around not swimming then re ajusting himself and then just floating off again then after a couple of hours he died and he was really swollen in his gut , the barb was aswell , they were both fine yesterday and had no problems what happened to them?

Answer 1

I think hopeless nail the problem, they both had dropsy. Dropsy is a sign of any one of several bacterial infections in the fishes belly that cause fluid to accumulate showing swelling. These conditions are generally hard to treat and it's always best to remove a fish showing this problem before it dies as the infection can spread easily if the fish dies in the tank.
