Right now they are are on a little bit of everything. Hikiari Cichlid Gold pellets, krill, ghost shrimp now and then, frozen brine, frozen beefheart, these pigs will eat anything.
Most of your fish are vegitarians. Be very careful feeding them some of this stuff, especially the beefheart. They will be very susceptible to getting bloat and dying of they eat too much of this stuff.
All you need is New Life Spectrum for these guys.
