Peppermint Shrimp are often sought after because they tend to eat small aiptasia in the reef. While most LFS will carry these, some are possibly mistakenly sold as Peppermints when in fact they are Camelback shrimp. Camelbacks have a hump that is quite distinct when the animal is viewed from the side rather than from above (as pictured here). However, I'm 100% postive this one is a Peppermint Shirmp. :) They do no harm to most corals, and fish tend to ignore them. They are usually only visible late at night with a flashlight, as they hide in the rockwork all day long.   Reef-safe.
