In plain words: Green star polyps look like a purple carpet covered in tiny glowing green stars. Each star is a polyp: a little animal with eight feathery arms. Hundreds of polyps share one stretchy purple skin, so the whole mat is really one big family.

About the Green Star Polyp (GSP) XL Rock

Green star polyps form a purple mat topped with bright green, feathery polyps, and this listing is an extra-large rock that is already covered. GSP is one of the hardiest corals in the hobby and likes moderate light and moderate to strong flow. It does not sting, but it grows quickly over rock, glass and slower corals, so keep the rock on its own island surrounded by sand.
