Keep in mind

These shrimp have a symbiotic relationship with various anemones and corals. The shrimp may eat a little flesh of the host now and then.
Its a good idea to keep these shrimp with a large host which can withstand the continual predation by the shrimp.

Should not be kept without a host.
