Browsing the website you posted, it looks more like the red silk coral, except it's orange, so it's an orange silk coral.
I initially had it under my MH lights, but last night I put a square piece of cardboard on the top of the tank, right above it, so light doesn't fall on it.
It tends to be a lot bigger when lights go off at night and before lights come on in the morning. I feed it phyto mixed w/ cyclopeeze. Has gentle to no current on it.
