I know the symptoms of when a platy is about to drop but i dont think they work for me... i came home today and i saw a platy fry! im pissed because i have 3 pregnant platys and out of the blue one gives birth? she wasnt aggressive, she wasnt hiding, she acted like a normal fish!!!!!! Now i'm scared cause now i dont know when my other 2 platies will drop!!! i saw 3 fry and managed to catch 2 (cant find other). So how do i know when the others are about to drop?? i need to isolate them 12-24 hours before they drop! my killifish probably ate the majority of the fry...
