Common name: Didemnid Tunicates

Didemnidae is a family of colonial tunicates often found in reef environments. These sessile invertebrates are known for their encrusting growth form, covering rocks and dead corals with a velvet-like layer. They exhibit a range of colors and can be quite beautiful, adding diversity to the reef aquarium. Didemnids are filter feeders, sieving plankton from the water, which can help maintain water quality. They have a symbiotic relationship with photosynthetic algae, Prochloron, which lives in their tissues and provides them with additional nutrients through photosynthesis.
