- Black body with a red central eyespot and long, thin, fully black spines; appears delicate but is well-defended.
- Nocturnal algae grazer that hides during the day and forages at night on algae and seaweed.
- Excellent algae controller for aggressive aquariums where other invertebrates may not survive.
- Defends itself by sensing nearby fish and orienting its spines toward threats; venomous with a sting similar to a bee sting.
- Very sensitive to copper medications and high nitrates; spine shedding indicates poor water quality; diet can be supplemented with dried seaweed.
