Commonly known as Sea Mat and Button Polyps, these corals prefer bright light, but are tolerant of lower light. Preferring moderate to strong current, Palythoas have a high reproductive rate and are very aggressive. Some of these species contain a strong neurotoxin which affects humans.

While most of these corals are brown to dark brown in color, a fair number of them contain elements in their tentacle tips, which fluoresces beautifully under actinic blue lighting.

These species are good starter corals.
