I have an extremely pg platy (wayyy overdue), who has so far delivered several dead fry - but is swimming frantically and has to stop every few minutes to rest - basically "fish hyperventilating". Then when rested a bit, goes back to swimming like a maniac! She's obviously overdue on delivery for a reason now that I'm seeing dead ones being expelled. She's having trouble getting more out though - is there anything I can do to help her. I'm afraid she will die in the process of trying to get them all out. HELP!!??
