Common name: Discus coral

General information

The Radiant Sea Urchin, Zoopilus echinatus, is a striking and somewhat rare echinoderm that is known for its distinctive appearance. It has a globular shape with long, slender spines that can exhibit a variety of colors, including vibrant blues, purples, and reds. These colors can be quite intense, making it a visually appealing addition to the marine aquarium.

Care

Caring for Zoopilus echinatus requires a well-established aquarium with stable water parameters. They are sensitive to changes in water quality, so regular monitoring and maintenance are crucial. The tank should have plenty of live rock and a sandy substrate to allow the urchin to move around and forage for food. They primarily feed on algae, but in the aquarium, they may also accept prepared foods like seaweed sheets or sinking pellets.

Reproduction

In the wild, Zoopilus echinatus reproduces by releasing gametes into the water column, where fertilization occurs externally. In the home aquarium, breeding is rare, but with optimal conditions, it is possible to observe spawning behavior.

Habitat

Zoopilus echinatus is found in the Indo-Pacific region, typically in coral reef environments. They prefer areas with strong water movement and access to plenty of natural food sources. In the aquarium, replicating their natural habitat with proper flow and lighting will help maintain their health and vibrant coloration.
