When we got home from work today, one of the clownfish was lying on it's side next to a rock. It's breathing seems to be erratic. Every minute or two he charges out from his spot to swim next to the other clown for a bit, and then goes back to lay down. I checked him for signs of excess slime, discoloration, white spots etc, and he doesn't seem to have any of these brooklynella symptoms at all. Params: temp 81.3 (always keep the tank between 80-82) SG: 1.027 Amm: 0 nitrite: 0 Nitrate: 0 PH: 8.0 Other clownfish in the tank is behaving normally staying near the same area as the downed clownfish. Blenny is also acting normally. Does anyone have any ideas of what to do? I have formalin here if needed. I don't want to stress the fish out by trying 100 different things though.
