Common name: Bluebell Tunicate
General information
The Bluebell Tunicate, scientifically known as Clavelina viola, is a captivating invertebrate that adds a touch of elegance to any reef aquarium. These tunicates are known for their translucent, violet-colored bodies and their striking resemblance to a cluster of small, delicate bells or flowers. They are colonial organisms, meaning that each colony is composed of numerous individual zooids connected by a common tunic.

Care
Caring for Bluebell Tunicates requires a well-established aquarium with stable water conditions. They thrive in moderate to strong water flow which helps them feed on suspended particles in the water. It's important to maintain high water quality, as tunicates are sensitive to nitrate and phosphate levels. Supplemental feeding with phytoplankton or fine particulate foods can benefit their growth and health.
Reproduction
Clavelina viola reproduces both sexually and asexually. In sexual reproduction, they release sperm and eggs into the water column, where fertilization occurs. The resulting larvae settle on suitable substrates and form new colonies. Asexually, they can bud from the parent zooids, creating genetically identical clones that contribute to the expansion of the colony.
Habitat
Bluebell Tunicates are typically found in the Indo-Pacific region, often attached to substrates in shallow reef environments. They prefer areas with good water movement which facilitates their filter-feeding lifestyle.
