To go along with the fresh fruits and vegetables, I keep a mixed dish of TetraMin Tropical Fish Flakes, and HBH Hermit Crab Variety Bites which is a fine powder type food with Crude protein 15%, Crude Fat 10%, and Crude Fiber 7%. My Millies are always in there eating something, but I can't tell if its the hermit crab food or the fish flakes or both. Do you think I am wasting my money on the hermit crab food, and they are probably just eating the flakes, or you think they might be eating both?
