hey guys i have four jack dempseys and they are about 3 and a half inches, recently they seem to all be on edge keeping up towards the center of the water column. one i can identify is definitely female the other 3 i can not tell, how do i know when a male has paired up with my female, i have been noticing a slight bit more of aggression everyone seems to chase everyone when they are to close to each other, no fin biting of any sort yet though. i can take a video and upload it if you need to see the behavior.
