What is this? (1 Viewer)

Hi all I’ve been out and back in the hobby and my fish are still looking happy but the tank not so much… I thought that what has been invading it were aiptasia but I have doubts now… in addition to small starfish I have the picture here and wonder what these are? Thanks!

Can you circle what you're asking about?

All of the purple that’s covering the rock

Do the polyps have mouths? What about a skeleton? Looks a lot like ducan heads

 

[PoissonRouge]

Hard to say I’d say yes for mouth and no for skeleton. See closeup pictures. They spread like crazy!

I think you are right these are Duncan coral! Oh my they’re everywhere!! How am Into reduce the spread?

Duncans grow at the end of a branching skeleton, like a hammer or trumpet coral, so I don't think that's what these are. They definitely don't look like Aiptasia, a little like Mojano but those are usually more transparent, but they may be some kind of anemone.

Oh ok thanks. Well I guess the only way to get rid of it is to dry the rocks? I got an Australian Stripey and shrimps in hope they’d eat it but to no avail
