Genus
Common name: Star Ascidian
Scientific name: Botryllus
Botryllus is a genus of colonial tunicates commonly known as Star Ascidians or Golden Star Tunicates. These sea squirts form beautiful star-shaped colonies that can add a unique aesthetic to a reef aquarium. They are known for their vibrant colors, often in shades of gold, yellow, or orange, and their ability to encrust on various surfaces. Botryllus species are filter feeders, drawing in water to extract plankton and other nutrients. They are relatively easy to care for, requiring stable water conditions and moderate lighting. In the wild, they can be found in a variety of marine environments, often growing on rocks, shells, or other substrates.
