Common name: Magnificent Shrimp

General information

The Emperor Shrimp, Periclimenes magnificus, is a strikingly colored marine invertebrate known for its vibrant hues and symbiotic relationships. This small shrimp is adorned with a pattern of white, red, and sometimes blue, making it a visually appealing addition to any reef aquarium. It is a member of the family Palaemonidae and is found in the Indo-Pacific region.

Care

Emperor Shrimp are relatively easy to care for in a well-established reef aquarium. They require stable water conditions and plenty of live rock or coral to explore and forage on. These shrimp are not aggressive and can be kept with a variety of tank mates. They are scavengers by nature and will feed on detritus, leftover food, and sometimes parasites on fish, contributing to the cleanliness of the tank.

Reproduction

In the aquarium, breeding Emperor Shrimp can be a challenge. They have a planktonic larval stage which requires very specific conditions to survive. However, with meticulous care and stable water parameters, it is possible for hobbyists to witness the fascinating breeding behavior of these shrimp.

Symbiosis

One of the most interesting aspects of the Emperor Shrimp is its symbiotic relationship with various sea cucumbers and nudibranchs. It often rides on these hosts, gaining protection and mobility, while also picking off food particles from the host's body. This commensal relationship adds an intriguing dynamic to the aquarium.

Habitat

Periclimenes magnificus is typically found in tropical coral reefs and associated with various invertebrates. They are often seen in shallow waters, where they utilize their hosts for transportation and as a platform from which to feed.
