Hi, I have 3 black convict fish and a 13 inch alge eating fish in a 55g aquarium, my problem is a weird one. I have 2 females and 1 male and the females have paired up and are laying eggs together in their makeshift cave but not letting the male around. Is this unusual? I know they are the females becuase they both have orange on their bellies and the male doesn't. Plus they have both been laying eggs for 2 weeks but no fry yet. Should I seperate them or what? Any help would be great.
