they arent normally picky eaters.
they are omnivores, and the last batch i had a few years back ate flakes, micro pellets, atisons betta starter, freezedried daphnia, freezedried bloodworms, frozen daphnia, algae wafers, and any shrimplets/microinverts they could catch.
these are probably just picking away at the micro fauna, and probably dont have their full appetites back yet either.
