General information

The Sexy Shrimp, scientifically known as Hamodactylus noumeae, is a small and colorful crustacean popular among reef aquarium enthusiasts. Its common name derives from the unique way it moves, with a characteristic "dancing" motion of its abdomen, which has earned it the moniker 'Sexy Shrimp'. This species is known for its vibrant coloration, typically featuring a translucent body with white spots and red or purple accents on its tail.

Care

Sexy Shrimp are relatively easy to care for, making them suitable for both beginner and advanced hobbyists. They require a well-established aquarium with plenty of live rock and hiding places. These shrimp are omnivorous and will accept a variety of foods, including frozen and flake foods, but they particularly enjoy small meaty foods like brine shrimp or mysis. It's important to feed them small amounts several times a week.

Reproduction

In captivity, Sexy Shrimp can reproduce if kept in a group with both males and females present. They have a unique breeding behavior where the female carries the eggs until they hatch, releasing free-swimming larvae into the water column.

Symbiosis

Sexy Shrimp are known to associate with various anemones, much like clownfish, though they do not form as tight a bond. They can often be found perched on or near anemones like @species:entacmaea-quadricolor, benefiting from the protection the anemone provides while also scavenging for food particles.

Habitat

Hamodactylus noumeae is native to the tropical waters of the Indo-Pacific region. They are typically found in coral reefs and lagoons, often seeking refuge among the tentacles of anemones.
