I have a small piece of rock, about 1 -1 1/2 pounds and about a month ago a saw something growing..now it's over dubble the size but i have know idea what kind of coral it is.. it might be some type of brain coral?

heres a pic: It is a brown ish colour on the outter ring, but the middle is almost a neon green, and has litle green hair like thing that come out of it!

Almost definitely an Acanthestrea genus coral, although the species is a little up in the air so to speak. MIGHT be a lordhowensis but I doubt it.
