So just picked up a coral from my lfs and when I put it in qt I noticed these guys in the bag water. Any clue?

They are like spider crabs mite things...

That's zoa spiders! Pycnogonids.

Do these guys eat acros, or are they strictly zoa killers?

 

[Lionfish Lair]

No they don't eat acros, but will eat any soft-bodied corals and are not specific to zoas. They basically pop their proboscis into the coral, sucking out its juices like a mosquito.

So the green thing they are clinging to, would that be their eggs?

 

[Lionfish Lair]

If you look really close, you should be able to see individual eggs. From afar, that's what it would look like, though. :-(

Thank you very much for your help.
