Common name: Pycnoclavella diminuta
General information
Pycnoclavella diminuta is a species of colonial ascidian, or sea squirt, found in tropical marine environments. These small, encrusting organisms are known for their ability to filter feed by drawing in water through their siphons, extracting plankton and other nutrients before expelling the filtered water back into the environment.

Care
In the aquarium, Pycnoclavella diminuta requires stable water conditions with low to moderate flow and clean water to thrive. They are filter feeders and benefit from the presence of fine particulate organic matter or phytoplankton in the water column. It's important to avoid placing them in direct, strong water currents, which can prevent them from feeding effectively.
Reproduction
Pycnoclavella diminuta reproduces both sexually and asexually. In sexual reproduction, they release sperm and eggs into the water column, where fertilization occurs. Asexually, they can bud new individuals from the edges of their colonies, allowing for rapid expansion under favorable conditions.
Symbiosis
While not known for engaging in notable symbiotic relationships like some other marine invertebrates, Pycnoclavella diminuta contributes to the overall health of the reef ecosystem by filtering water and providing a food source for some specialized predators.
Habitat
This species is typically found on reef substrates, often in shaded areas or under overhangs to avoid direct sunlight. They are distributed in warm, tropical waters and can be found at various depths, often in association with other benthic organisms.
