Peppermint Shrimp, Lysmata Sp.

The Peppermint Shrimp is best known for its natural ability to manage
nuisance Aiptasia, or glass anemones. Keep in mind that some individual
Peppermint Shrimp are better at managing aiptasia while others may not
be interested in aiptasia at all. Though considered part of the
“cleaner” grouping of shrimp, Lysmata wurdemanni is more of a
scavenger. The Peppermint Shrimp picks its way around your aquarium and
live rock to consume detritus, uneaten food, and decomposing organic
material. This ornamental member of the Hippolytidae family is brightly
colored with a creamy white body striped with several thin and distinct
longitudinal red bands.

Also known as the Veined or Caribbean Cleaner Shrimp, the Peppermint Shrimp is sometimes confused with its Pacific cousin, Rhynchocinetes durbanensis.
However, that shrimp has a pointed nose and inter-spaced white stripes
over its body. In the wild, Peppermint Shrimp are usually found in the
vertical shafts of the reef. Some even take up residence in the core of
pipe sponges. The Peppermint Shrimp does best in home aquariums with
live rock, ample places to hide, as well as open areas to scavenge.

Peppermint Shrimp are quite social and very peaceful towards most reef
inhabitants. Like other invertebrates, the Peppermint Shrimp cannot
tolerate copper-based medications or high nitrate levels. It also
requires supplemental iodine to encourage proper molting of its
carapace.
