Common name: Green Star Polyps

General information

Green Star Polyps (GSP), scientifically known as Clavularia viridis, are a popular soft coral species among reef aquarium enthusiasts due to their vibrant green coloration and ease of care. They are part of the Clavulariidae family and are known for their ability to rapidly cover surfaces with a mat of small polyps, creating a beautiful, starry effect.

Care

GSP are hardy corals that are well-suited for beginners. They thrive in a range of lighting conditions, from moderate to high, and can adapt to various water flows, although they prefer moderate to strong flow to keep their polyps free of detritus. They are not demanding in terms of water quality, but stable conditions and regular water changes are beneficial.

Reproduction

In the aquarium, Green Star Polyps can reproduce asexually through fragmentation. Pieces that break off from the main colony can attach to new surfaces and form new colonies. This ease of propagation makes them a favorite among hobbyists looking to fill out their aquascapes or trade with other reef keepers.

Symbiosis

While GSP do not have notable symbiotic relationships like some other marine organisms, their rapid growth can provide shelter for small invertebrates and fish within the reef aquarium.

Habitat

Clavularia viridis is found in the Indo-Pacific region, often in shallow waters where they can form extensive mats over the substrate. They are commonly seen on reef slopes and in lagoons, where they receive ample light and water movement.
