Periclimenes pedersoni
Pederson Cleaner Shrimp

They are from the Caribbean so they would be only available from through LA shipments or direct.
2.5 cm
A cleaner associated with Codylactis gigantea, Bartholomea annulata, and Lebrunia danae anemones.

It has many similar looking relatives from the Indo Pacific. Unfortunately anemone shrimp are often sold under generic "Anemone shrimp" , so you have no idea what you'll get until it arrives.

They are very attractive and active. Be wary of larger fish as they may eat them regardless of them being cleaners. They will clean your fish occasionally. It differs from shrimp to shrimp IME. They are perfectly reef safe and will come shooting out of the reef when food is added. They will eat anything you give them.

They would be great for Micro/Nano reefs under 20 gal.

Personally, I'd like to see more reefs with anemone shrimps scrambling through the corals.[/i]
