Graymatta: neons breed quite readily its just the eggs must be kept in the dark as well as the fry, if you have other fish they will eat eggs/fry, the neons will eat their own eggs/fry
zoo minsi: Black skirts lay eggs, same with the neons except minus the darkness. Their fry are raised like normal egg laying fry, infurosia, bbs, crushed flake food, etc. Black skirt females are usually bigger than males and yes their stomachs always look as if they are gravid. Your fish isn't sick. Oh and LUCKY!!! you can keep ferrets T -T. They're illegal in CA
