The Buffet Method

In the wild, hermit crabs eat something different every day.

Build a small daily buffet with Complete Meals, Single Ingredients, and The Core: green sand, worm castings, and calcium.

Offer a small pinch of each food. Let your crabs choose.

Build a fresh buffet every day.

Nature never serves the same plate twice.
