description Scarlet Cleaner Shrimp Overview

Lysmata amboinensis, commonly known as the scarlet cleaner shrimp, is a marine crustacean native to the Indo-Pacific region. Recognizable by its bright red body and long white antennae, this species establishes cleaning stations on coral reefs where it removes ectoparasites and dead tissue from fish. The shrimp engages in mutualistic symbiosis, relying on fish for food while providing a cleaning service. It is highly popular in the marine aquarium trade.

help Scarlet Cleaner Shrimp FAQ

What does a scarlet cleaner shrimp actually clean from fish?

Lysmata amboinensis picks at external parasites, dead tissue, and debris when fish visit its cleaning station. The shrimp advertises the service with conspicuous antennae and rocking movements.

Will scarlet cleaner shrimp cure marine ich?

No, cleaning behavior cannot reliably eliminate Cryptocaryon irritans from an aquarium or remove every stage of its life cycle. Infected fish require a proven quarantine treatment rather than reliance on Lysmata amboinensis.

Is Lysmata amboinensis safe in a reef tank?

It is widely kept in coral reef aquariums and is generally considered reef-compatible. A hungry individual may steal food from corals, so targeted feeding and observation are still useful.

Can two scarlet cleaner shrimp live together?

Pairs are often maintained successfully when the aquarium provides enough space, food, and hiding places. Lysmata amboinensis is a simultaneous hermaphrodite, so two mature individuals can alternate reproductive roles.
