When can I move baby Black Mollies in with adults?
You can move them in with the adults as soon as they’re big enough that they won’t fit in the adult’s mouth. Female livebearers have the ability to store sperm, so from 1 encounter with a male, a female can keep reproducing for up to 6 months-with no male in the tank. Not to mention, it’ll be awhile before you’re able to tell if your fry are male or females. If there’s any males, they’ll definitely go after the females-mother or sister or whatever, they don’t care. And, 5 gallons is too small for even 1 molly. I’d suggest looking into a tank upgrade for them.
