My little guys ate live black worms in the LFS. I started with "my" tank raised live bearer's. Got them use to the feeding hatch and being hand fed. Then would through a pellet in and they would smack it. Just like it say's some place in hear. Plus I had 2 little white tiger Oscars showing that all things coming out of the hatch is food. They don't get feeders any more, They like freeze dried krill, pellets 2 kinds and earth worms. And eat cut up frozen cocked shrimp.
