I woke up this morning to dead clown fish. They are in a 20 gallon with a 15 gallon sump with 20 lbs of live rock. Everything and I mean every thing as far as water quality is up to par. They have no bite marks as if a bristle worm attacked them so that is a no go there. The only thing is that they were in the process of breeding, can they die from wild clown breeding? It is odd that they died in the same night. PLEASE HELP ME!!!
