Common name: Red Sea Star

General information

The Red Sea Star, scientifically known as Fromia nodosa, is a striking marine invertebrate that adds a splash of color and diversity to the reef aquarium. This species is characterized by its vibrant red coloration with lighter nodules or bumps across its surface, which gives it the name 'Nodose Sea Star'. It is a relatively small sea star, typically reaching about 4 to 6 inches in diameter.

Care

Fromia nodosa requires a well-established aquarium with plenty of live rock for grazing and hiding. They are sensitive to water quality and require stable conditions with low nitrate levels. It's important to acclimate them slowly to avoid shock from changes in water parameters. They feed on detritus, small organisms, and sometimes on coraline algae. Supplemental feeding with finely chopped meaty foods can be beneficial, especially in tanks with limited natural food sources.

Reproduction

Reproduction in Fromia nodosa is not commonly observed in the home aquarium. In the wild, they reproduce by releasing gametes into the water column, where fertilization occurs. The larvae then go through a planktonic stage before settling to the substrate and developing into juvenile sea stars.

Habitat

The Red Sea Star is found in the Indo-Pacific region, particularly around the reefs of the Red Sea. They inhabit various reef environments, often seen on hard substrates and among corals at depths ranging from shallow waters to about 30 meters deep.
