About this crab

Pom Pom Cheer Crabs have tiny pom-pom claws and curious habits. They need a secure lid and carefully chosen tank companions because they can eat small shrimp and snails.

Is this right for me?

This crab needs extra planning. You must provide a secure lid, hiding places, and tank companions it will not harm.

Getting your tank ready

Use an aquarium that has completed its cycle: helpful bacteria in the filter must be established to break down animal waste. A newly filled tank is not ready for animals just because the water looks clear. Fit a secure lid and provide hiding places. Offer suitable foods that sink so the crab can reach them.

Keeping it with other animals

This crab may eat small shrimp and snails. Do not choose it for a tank where you need every shrimp or snail to be safe.

What you get

Approximate purchase size: 1/2–1 inch.
