Recently one of my clownfish disappeared.. What I think happened was he died and my CUC or pufferfish finished him off.. :-( I am building a 55 gallon and i really liked the clownfish in a pair. My question is, if I added another clownfish to the one that i have, will they fight? There both ocellaris clownfish, the old pair were mated, i believe the male died.. So its just the female right now
