What coral is this?

[mredwin25]

This came on a piece of live rock awhile ago and it’s growing, what is it?

Clove polyps, could be invasive. What colour are they? Blue?

 

[fragit]

Hard to tell exactly but looks like a clove polyp

 

[BighohoReef]

Could be clove if it's growing wild

 

[Brad Waddell Wrath's Reef]

I would agree, blue clove polyp. Looks nice until your entire tank is infested with them.

The polyps look more like a pipe organ to me- does it have a red skeleton base?

 

[vetteguy53081]

I too believe pipe organ. I also have clove polyps and they are Not evasive and not spreading
Picture is Very blue. Some white lighting would help verify what we are all looking at

 

[mredwin25]

they’re more like a purple color, not growing wild, slow growth
