The Black Urchin has a body which is predominately black with a red eyespot in the center. The spines on these urchins are long, thin and completely black. These urchins are excellent algae controllers for an aquarium housing aggressive fish.
The Black Urchin will hide during the day and only come out at night to forage for food such as algae and seaweed. These urchins are an excellent algae controller for an aggressive aquarium where other invertebrates would be eaten. When approached by a fish, these urchins will sense their presence, and will defend itself by directing its spines towards its offender.
Be aware, it is venomous, but the injury is not serious.
The diet may be supplemented with dried seaweed.
