Shell eating criktos

Shell eating criktos are small worms that live in the sand, they get attracted to shells of dead carrabi and they only eat the shells of the dead ones, not live ones. Criktos are about 1 inch wide at their largest and are orange with yellow stripes. Criktos are usually small in number and their size depends on the amount of shells that are in the water. Criktos get nutrients from calcium and they sometimes consume fresh shrimp molts. These worms are kept as pets by some because of how cool they look.
