Have been feeding mine, cichlid pellets, and occasionally they eat some of the koi pellets I feed to my barbs. Freeze died tubifex and brine shrimp, as a treat a couple of cockles, but have just dicovered that they mad for frozen brine shrimp. Usually my Frontosa's are slow eaters (I have read that this is usually the case). I got the fish really cheap as they had been underfed and not looked after very well so have been trying to condition them. Thier belly's are now the shape they should be rather than massivly indented, but I've been increasing thier diet slowly to re-build thier appetite. Was totally shocked at thier reaction to the frozen brine shrimp. I'm gonna try them on a little raw beef heart and if they like it, will feed them this once a week! How long have you had ur Frontosa's and what size are they? Do you know how to sex them?
