I have had two false percula clowns together for a little over a week. I had a smaller one for about a week before i got a bigger one. i figured since one was bigger, it would quickly become more dominant than the samller one and become the female and they would pair. they have been fighting a little, especially when i feed them, so i think they are pairing. but they spent today on seperate sides of the tank, completely ignoring each other. they sleep in the same spot, but now if the little one gets too close to the big one, he is chased away. Is this just part of the pairing process, or is there a chance they wont pair up?
