Hermit crabs and reef crabs for sale

Crabs are a key part of any cleanup crew. Our hermit crabs for sale include blue leg and scarlet hermits, which eat algae and leftover food. We also carry emerald crabs, which are known for eating bubble algae.

Caring for crabs

Hermit crabs need spare shells to move into as they grow. Without them, they may take a shell from a snail. So keep a few empty shells in the tank.

Most small crabs are reef safe. Larger crabs, however, can become opportunistic, so watch them as they grow.

Common questions

How many hermit crabs should I add?

About one small hermit per two gallons is a common starting point. Pair them with snails for a balanced crew.
