I find beefheart to be more cost effective than pellets. All my fish eat beefheart. There was one indo dat that didn't want to eat the beefheart so I add raw shrimp into the mix and that is what he eats. They are nice and fat. I do give them a treat of freeze dried krill.The reason they started eating beefheart is because of the fact that I have them with bichirs, and that is all I feed the bichirs and the ATF. I tried the Hikari carnivore pellets, but no success. I have to agree that the more you care the longer it takes for them to eat pellets.
