I've had my ocellaris pair for about 3 years now. They live happily with their BTA. They have not spawned yet, but I noticed them pretend spawning? I didn't realize they would do this. They both cleaned the area, then the female would pretend to lay eggs then the male would pretend to fertilize them. They did this on and off all day. Is this something common or are mine just different, or is something wrong?
