Help - what is this coral?

[ChicagoReef]

About 10 years ago I had a spec of green less than 1” by 1” and ten years later it is over 24”. I chopped a bunch off again today. Branches are thicker than my thumb.

thanks,
Mark

Hydnophora?

It looks similar to the hydnophora colony I had years back. It was king of the tank.

Thanks - that looks like my coral - just looked it up. Looked cool at first, aggressive and grows really fast.
