I feed my larvea chopped up pieces of live blackworms. The pieces wiggle and they eat them. There are other thing you can use like live daphnia and live brine shrimp. But am dont use those. I just use the live blackworms. Feed them everyother day. Let them eat a couple of pieces, just drop it infront of there face with a tweezers. Mine are so used to the tweezers, that they will eat right off it. When they first hatch, they wont need to eat for a couple of days, so just keep trying till they eat.
