i know its a closed goni as im sure it came from concept if so then its def a closed red goniopora.

your favia will appreciate alot of light and moderate flow , ive grown that particular piece from a skin flap maybe 3yrs or more ago ,and that frag came from my colonie, very hardy and can take alot of light , not all favias are similiar in care though.

small sweepers that pack a good punch as well:P:P
