Small green heads?

[craiguk]

Two bumps, with small flower heads with a green centre. Both are 0.5cm across, right below a large finger leather. Almost like mini zoas... what are they?

Look like firework clove polyp to me but I'm no expert

Could be. Had some in the tank a while ago. They didn't fair well - never knew why. Nowhere near this spot and have been gone for a year!

They look like a gsp to me not sure which variety but I have seen some in stores like that

Possibly colonial hydroids, but since you had polyps in the tank before, that's probably more likely
