Well, if you plan on keeping them, then you can just net them out and put them in another tank (if you have one) if not then you can purchase a larger breeder net. You can feed them crushed fish food of any kind, and you can also feed them egg yolk. First you just hard boil an egg, then you peel the outer shell off, then take the hardened yolk, fill a container with about 1/3 cup of water, then you mix. You can put this in a container and it should last a week or two. You can feed the fry 4-6 times a day. I feed mine 4 times a day in small amounts. Hope this helped!
