Is it poss to ID this please. Had to arrange my live rock and when I turned a piece around this was growing on it. Impossible to see it when rock was in place.
Hope you dont mind a few photo's

This one is pretty easy. Acropora tenuis. It can be distinguished from similar species by the rosette arrangment of the radials.

Thankyou very much.

It may be easy for you, but until a while ago I thought radials were tyres, or at least they are in the uk. .
I am trying to learn though.

Once again thanks, really appreciated.
