Variegated Urchin (Lytechinus variegatus) saltwater invertebrate

Variegated Urchins are active Western Atlantic grazers that consume algae across rock, glass, and substrate. They can become larger and stronger than a small Tuxedo Urchin, so leave adequate grazing area and secure frags and light rock pieces. Keep them in a mature aquarium with stable salinity, normal reef mineral balance, and no copper exposure.

Peaceful but physically strong. Like other collector-type urchins, it may pick up shells, algae, or loose décor while moving through the aquarium.
