HusbandryDescription: Colonies are composed of long tubular corallites which bifurcate at irregular intervals, and which face upward. Corallites are round, 10-14 millimetres diameter, and have well developed septa arranged according to Pourtalès plan. Columellae are broad and deep seated. Walls are composed of porous coenosteum. Tentacles are extended day and night and may form a continuous mat concealing the shape of the underlying colony.
Color: Green or blue-grey.
Habitat: Usually occurs in water over 20 metres deep, attached to a solid substrate but in areas where soft sand predominates.
Abundance: Rare but conspicuous.
Similar Species: Tubastrea species have similar corallites, but are azooxanthellate.
