Common name: variegated urchin

General information

The Variegated Sea Urchin, scientifically known as Lytechinus variegatus, is a colorful and active echinoderm that is popular among reef aquarium enthusiasts. This species is known for its striking appearance, with a round body covered in variable colored spines that can range from green to purple. They are often found in shallow waters and are an important part of the reef ecosystem, helping to control algae growth.

Care

Variegated Sea Urchins require an aquarium with plenty of live rock and algae for grazing. They are excellent algae eaters and can help keep the tank clean. However, they may also inadvertently consume or damage some corals or invertebrates, so they should be monitored in a reef tank setting. Stable water conditions and regular water changes are essential for their well-being.

Reproduction

In the wild, Lytechinus variegatus reproduces by releasing gametes into the water column, where fertilization occurs externally. In the aquarium, breeding is less common but can occur if conditions are favorable. Hobbyists interested in breeding should provide a mature, stable environment and consider the seasonal timing of reproductive cycles.

Habitat

The natural habitat of the Variegated Sea Urchin includes seagrass beds, rocky substrates, and coral reefs, primarily in the Caribbean Sea and the western Atlantic Ocean. They are typically found at depths ranging from the intertidal zone to about 70 meters.

In the aquarium, they require ample space to roam and a variety of surfaces to graze on. It's important to ensure that the aquarium setup mimics their natural environment to some extent, providing both hiding places and open areas.
