We have a 75 gal. tank. Here are the levels: Nitrite 0.25, Ammonia 0, PH 8.2, Nitrate 20 and salinity is 1.021 and temp is 76-78. There are also alot of small bubbles on the top of the water.
All of our fish are fine except the clown has been acting strange...his mouth is open and he is breathing heavy....his aggression is gone and he doesn't go in the anemone as much as he use to and he is not eating like he use to. What should we do? He is my favorite fish and I don't want anything to happen to him......what is wrong with him?
