I have blue ram fry and I don't know how to feed them. The rep at my local fish store said they use New Life Baby formula... This stuff floats, the babies are on rocks. I can't get it to work to feed them.
There is something called first bites you can get which is a powdered food. You can also mash your pellets to make a powder on your own. I believe egg yolk will work too, not a lot obviously...oh and hard boiled I mean. Break it down to a powder. Baby brine shrimp works also or vinegar eels.
