My polys eat live fish, bloodworms, crayfish, cut squid, market raw shrimp, earthworms, and chicken hearts. All live foods are gut-loaded before being fed out.
most of my bichirs eat meaty frozen foods like shrimp & mussles.. occasionally they eat beefheart as well but most of them love to eat superworms when i give them as treats..
im having problems with my endlicheri though which does not eat much and is always hidding..
