The Hinge-Beak Shrimp is a fascinating marine shrimp known for its unusual hinged, forward-pointing beak and striking red-and-white striped pattern. Also commonly known as the Camel Shrimp or Dancing Shrimp, it is an active and interesting addition to suitable marine aquariums.

Unlike cleaner shrimp, Hinge-Beak Shrimp are primarily scavengers and should not be confused with true cleaner species. They spend much of their time exploring live rock, caves and crevices in search of food.

They are best suited to peaceful fish-only or carefully selected marine systems and should be provided with plenty of hiding places and a varied diet.

Common Mistakes

Assuming they are Cleaner Shrimp

Despite their similar appearance and common name "Dancing Shrimp", Hinge-Beak Shrimp should not be treated as a cleaner species.

Keeping them with vulnerable shrimp

They may compete aggressively with other small shrimp, especially in confined aquariums.

Not providing enough hiding places

Live rock, caves and crevices are important for providing shelter and reducing stress.

Underfeeding

Although they are scavengers, they should not be expected to survive solely on leftover food. Supplement their diet regularly.
