Pest id: not pycnogonid, micro brittle, or zoa spider

[gdemos]

Researched everywhere could not get a positive ID. Saw some old threads with similar descriptions but the pictures were stripped from th thread

I honestly don't think this is any type I'd brittle star because it walks / crawls like a spider doesn't wiggle like a brittle.

I firmly believe it is eating tissue on acros. Only visible at dark and there are a few not a ton.
Wish I could get a better picture but anytime I can remove it from the acro they more or less deform.

Anyone know?

Looks similar to some of the acro spider pictures I have seen a while ago when I was reading up on pests. Maybe someone with experience with them can chime in. Good luck if that's what it is.

Acro spiders are much different than zoa spiders.

From what I have read there are countless species of 'sea spiders'. Searching on what I might call an acro spider. (because they look like a spider and theyre on my acros) takes me to articles showing some pics of various pycnogonid.

Anyone have better idea?
Suggestions on eradication?
Six line wrasse?

Thanks. -Greg
