What should I feed Hermit Crabs?

Halibut feed on almost any animal they can fit in their mouths: animals found in their stomachs include sand lance, octopus, crab, salmon, hermit crabs, lamprey, sculpin, cod, pollack and flounder. Halibut can be found at depths as shallow as a few metres to hundreds of metres deep, and although they spend most of their time near the bottom, halibut will move up in the water column to feed. In most ecosystems the halibut is near the top of the marine food chain. In the North Pacific the only common predators on halibut are the sea lion (Eumetopias jubatus), the orca whale (Orcinus orca), and the salmon shark (Lamna ditropis).
