Peppermint Shrimps are often kept in reef tanks to eat the pest Aiptasia anemones.
Mine do not seem to have a taste for it.
They are often kept in large groups in the hope that they will group spawn.
Sometimes the larvae are just eaten by other tank inhabitants, but some people do manage to rear them in captivity.
