  Black Longspine Urchin (Diadema setosum) 

The Black Longspine Urchin is a very interesting addition to any aquarium.

It has long, thin black spines that extend from its body, and rows of blue spots in a symetrical design across its body.

The anus of the long spine urchin looks like an eye on the top of the body, with a bright orange ring in the center.

While the body itself is usually only about 2 to 3 inches in diameter, the spines can grow three to four times this length.

During the day, urchins will find a corner or hiding spot to rest.

At night, they will roam about the tank searching for food and algae on the substrate, rockwork, and glass.

Food and Diet:

The urchin is best kept in an aquarium where it will have ample supplies of algae to eat.

Recommended Minimum tank size: 1 gallon or larger

Level of Care: Easy

Approximate Purchase Size: 1" to 2"

Reef Compatibility:Very good
