While this species will supplement its diet with meaty foods, its primary source of food is marine algae.

Feeding & Nutrition
Scarlet Reef Hermit Crabs are primarily scavengers and tank cleaners, where they will eat most forms or algae and any leftover meaty foods that make it to the reef or substrate. If there is insufficient algae to eat, their diet must be supplemented with dried seaweed. Scarlet Reef Hermit Crabs will also accept many other types of meaty foods; such as, frozen, flake, freeze-dried or other forms of meaty preparations.
