Ok i have now 4 false perc clowns. The one i started with is sideways at the top of the water...now i think this is because of the nitrites, there a little high right now about .25 or so, ive been doing 40% water changes and he still stays up at the top the other 3 are as happy as can be swimming all around. Is it the nitrite? o btw all 4 of the percs are from the same tank(captive bred) at the LFS just got them at diffrent times but all within a weak.
