Try live rinsed brine shrimp, daphnia, and caddis/mayfly larvae. Their diet in the wild while small is mainly tiny inverts and tiny fish fry. Baby gambusia are ideal.AmazonPredator said:That seems to hold true. The larger ones eat alot better than the smaller ones. Is there nothing I can feed the smallest ones? The one that eats the best is the largest one at about 5''. They and a couple of the others eat floating pellets well, then a few seem to have no appetite at all. I also lost one or two to ich.
