I have around a dozen platy fry in a breeder that are about a week old. How long do I keep them in the breeder before I can remove them and put them in with the other fish in my tank (which is mostly platies and danios)? I don't want them to get eaten! Also, I have a live plant in the breeder for them and I feed them ground up fish flakes. Is that enough for them? How many times a day should I be feeding them?
