Found another one

[goat585]

I found this guy in the bottom of my quarantine tank. I think this guy does not look as friendly as the last one I found. Can you please help ID it?

Thanks

Looks like a xanthide crab...definitely not reef safe.

Yep, that's a xanthid, probably something in the genus Actaeodes. Species in this genus:

• Have a broad carapace - much more broad than deep (front to back), with a:
• ______Narrowing at the posterior, hind end
• ______Rumply/furrowed surface
• ______Somewhat beaded, or granular texture
• ______Either a light/slight covering of short hairs (can appear downy-like) or scattered stiff hairs (typically either within the furrows or on the granules themselves)
• Have short legs with varying degrees of hairiness and "beading"
• Have heavy claws with like variations.
• May have red eyes
• Are omnivorous, but at least one species has been reported to include zoanthids in its diet
• Tend to remain small (typically ~1-2.5" total carapace width)
• Are fairly frequent hitchhikers

That pretty much sums up what I know about these guys. If you haven't already, I'd definitely leave it out of the display (perhaps put it in a sump - not in a 'fuge though), or find it another home. Here's a link to an example of this genus (Actaeodes tomentosus): http://www.flmnh.ufl.edu/reefs/guamimg/crustacea/xanthidae/Pages/Image1.html
There are also a ton of photos of these crabs on the web - just plug in Actaeodes into any image search engine and you'll be good to go!

Take care,
-Lynn

Thanks. it does have red eyes and looks very similiar to the photo. Its in my quarantine tank now not causing any issues so he can stay there for a while.

Thanks for the information

You're very welcome,Tom. It sounds like you've got the crab in the best place possible for now!
