Common name: Bluebell Tunicate

General information

The Bluebell Tunicate, Clavelina detorta, is a colonial tunicate often found in the aquarium trade for its striking blue color and unique appearance. Tunicates, also known as sea squirts, are sessile filter feeders that belong to the subphylum Tunicata. Clavelina detorta is particularly noted for its translucent blue zooids connected by a common stolon, giving the appearance of small blue bells or flowers.

Care

Clavelina detorta requires a well-established aquarium with stable water conditions and moderate to strong water flow to mimic their natural environment. They are filter feeders, so providing a constant supply of phytoplankton or other fine particulate foods is essential for their health. They do not tolerate high levels of nitrates or phosphates well, so regular water changes and efficient filtration are important.

Reproduction

In the aquarium, Clavelina detorta can reproduce both sexually and asexually. Sexual reproduction involves the release of gametes into the water column, while asexual reproduction occurs through budding, where new zooids form from the stolon. This can lead to the formation of new colonies within the aquarium if conditions are favorable.

Habitat

Clavelina detorta is typically found in shallow waters on reef slopes or under overhangs where there is strong water movement. They are distributed in the Indo-Pacific region, often forming dense aggregations that contribute to the biodiversity and aesthetic appeal of the reef ecosystem.
