The Urchin Clingfish is also known as the Yellow Stripe Clingfish, and originates from the reefs of the Western Indian Ocean. Its slender body is reddish brown with a pair of yellow stripes that run the length of the fish. The tail is round in shape and features a yellow spot within the center.

A 30 gallon or larger aquarium with plenty of live rock and corals provides a suitable environment for the Urchin Clingfish. This fish often lives in close association with a Long-spine Sea Urchin or branching corals. It uses this association for both protection and for food. The Urchin Clingfish also preys upon parasitic bivalves that attack various species of corals.

As a carnivore, the Urchin Clingfish will thrive on a diet of meaty foods such as finely chopped fresh or frozen marine fish, squid, mysid shrimp, vitamin-enriched brine shrimp, and frozen carnivore preparations.
