Zoa pest help

[lee_d_m]

Hi

I have these fluffy looking pests that managed to kill all my Zoas a few months back. Now, even without any Zoas they are still going strong and multiplying, but don't seem to be doing any coral damage thankfully.

I was hoping that someone could ID them please

Just realised the photos are all upside down, not sure how to change it though, can anyone help ?

They just look like small patches of Xenia or something similar to that IMO. Are they crawling around at all? I do see some Aiptasia in the pictures though.

It’s just below the aiptasia in the second picture (if you turn it the right way up). They do move around and are multiplying slowly. They also fluoresce very slightly under blue lights.

Some sort of Nudibranch perhaps? The link below might help. (Nudibranch-Predatory #1)
