Acro crab?

[Tattoonick]

This guy came in on a millepora and has happily been chilling there for a couple months. Never seen him leave or cause any issues. Just today I saw him just to his next door neighbor and was able to get a good shot of him. Does he look like a true acro host crab, or more like a xanthid?

Nope, it would move it to your sump.

As a general rule, hairy crabs are destructive. I'd get him out.

 

[Tattoonick]

Cool, I yanked him out.
