What is it?

So this has been growing on my rock for a while now. I started real small and I've noticed it really bloomed. Any clue what it could be. Bad? Good?

Looks like Anthelia.
It's a basic soft coral that is a common hitchhiker. Keep it under control or it can really become an invasive coral as it does tend to spread fast.

Thanks for the heads up and info!

GSP?

definitely anthellia. It grows like a weed and chokes out other corals if it can. Try your best to keep it in check. If it touches another rock, it will grow on to that rock. Those little polyps will grow four to six times as big in the oncoming months!

Thanks! I'll make sure to watch it and keep it contained to the one rock
