Whats Growing On My Acan?!?

[Chrisjordan004]

As the title suggests, I purchased an Acan in a Livesale and it came with a flower looking buddy. Anyone know what it is? Friend or foe?

Honestly looks like a small anthellia/daisy polyp, they grow like GSP so unless you want that I'd remove it, though to be sure, @ISpeakForTheSeas?

It does look like an octocoral polyp to me; I can't tell if the tentacles on the polyp are feathery or just bulbous though (so clearer pics under white light may be useful for a proper ID here).

If the tentacles are feathery, then there's a good chance it's a very fast growing (fast to invasively fast) coral; if they're bulbous, then I'd need clearer pics to be sure it's actually an octocoral.

I'd get rid of it. Looks like it has potential to take over the tank. It obviously grew so fast that it hopped on that disk in a limited amount of time.
