Live Sand Hitchhiker ID Help

[CheifReeferNB]

If recently purchased some live sand from gulf live rock. It’s a very rubble like substrate and has come with a ton of critters. I need some help identifying them. I’ve attached some images below. Any help would be appreciated!

Crab 1:
Camouflaged red crab. Furry legs and a little red hat looking mark. Kind of looks like a jumping spider. Clinging on to that rock for dear life would not budge when I moved him around.




Crab 2:
Little all white crab. Scared of light and hides in sand.

Sorry, details are not clear enough for me with bifocals. Here is the list of hitchhikers that GLR post. You tell us what you have.

I’m thinking crab 1 is a decorator crab and the second one is a small porcelain crab. Can’t quite tell though.

For certain they are interesting, biodiverse & probably a beneficial member of CUC.

I would isolate them in some container they can’t crawl out of like a like tupperware side dish or plastic container. Until you’re sure they not harmful.

Hitchhiker crabs are definitely a trust, but verify, situation to me.
