Common name: ruby brittle star

General information

The Ruby Brittle Star, Ophioderma rubicunda, is a striking invertebrate known for its vibrant red coloration and long, slender arms. This species is a nocturnal scavenger, playing a crucial role in the cleanup crew of a reef aquarium by consuming detritus and uneaten food.

Care

Ruby Brittle Stars are relatively hardy and can adapt to a range of conditions found in well-established aquariums. They prefer a tank with plenty of live rock and a sandy substrate to hide during the day. It's important to ensure that the tank is free of aggressive fish that may prey on brittle stars.

Reproduction

In the wild, Ophioderma rubicunda reproduces by releasing eggs and sperm into the water column, a process known as broadcast spawning. In captivity, successful breeding is less common, but with stable water conditions and a mature tank, it is possible to observe their unique reproductive behavior.

Habitat

Ruby Brittle Stars are found in the Caribbean Sea and the Western Atlantic, from Florida to Brazil. They inhabit various marine environments, from seagrass beds to coral reefs, often hiding under rocks or within the reef structure during the day.
