Any ideas?

[sparky1708]

This just appeared in a crevice on some live rock. It inflates and then deflates if anything goes near it. Any ideas would be welcome

Cheers

Looks like a mushroom coral

I would say that is a majano anemone. A pest anemone one would address with a product like aiptasia-x.

[sparky1708]

Oh right. If I treat it with Aiptasia-X and it’s not a majano will it still kill it. I’d hate to kill off something that’s desirable as opposed to a pest

looking at it than looking again its harmless it looks like a green button polyp

[sparky1708]

Ok. Well I’ll probably leave it for a week or two then post updated fotos to see if opinions change as it develops. Thankyou for your reply

The aiptasia x prob won't do anything. I've had bta consume it without issues.
