Common name: Soft coral crab

General information

The Candy Crab, scientifically known as Hoplophrys oatesi, is a small and colorful crustacean that is highly sought after by marine aquarists for its unique appearance and interesting behavior. This species is named after its discoverer, and its vibrant hues and patterns allow it to blend seamlessly with the soft corals it inhabits, making it a master of camouflage.

Care

Caring for Candy Crabs in captivity requires a well-established reef aquarium with a variety of soft corals, particularly those of the Dendronephthya genus, which they prefer in the wild. Stable water conditions and a gentle water flow are essential to mimic their natural habitat. They feed on the mucus and tissues of soft corals, so it's important to ensure that their coral hosts are healthy and thriving.

Reproduction

Little is known about the reproductive habits of Hoplophrys oatesi in the wild or in captivity. However, like many marine invertebrates, they are likely to have a planktonic larval stage, which would make captive breeding a challenging endeavor.

Symbiosis

Candy Crabs exhibit a fascinating form of commensalism with soft corals, particularly those in the genus Dendronephthya. They not only use these corals as a food source but also as a means of protection and camouflage. The crabs often match the color of their host coral, which helps them avoid predation.

Habitat

This species is typically found in the Indo-Pacific region, residing within soft coral colonies at various depths. They are particularly associated with the vibrant and tree-like Dendronephthya soft corals, which provide both food and shelter.
