Peppermint shrimp are a nice addition to a reef tank. Like any shrimp, they require careful acclimation but once adjusted they are pretty hardy. Be careful, I have see some shops sell camel shrimp as peppermints. They look similar but the camel shrimp has been known to be a coral muncher. Camel shrimp have a hump on their back and larger, more forward eyes then a peppermint. Otherwise they are the same color and have a lot of the same markings.
