The AC hitchhiker ID thread (now thumbnailed)

ID Crabs Please help

Hi,
I'm new to saltwater and have had tank up for 6 months or so.
I have had several hitchhikers
The first one we saw when he was no bigger the your little finger nail.
I named him fuzzy wuzzy.
He has been a lot of fun to watch.
He has really grown.
His body is about the size of a silver dollar plus a couple inches on both sides for legs.
He looks like a spider.
What is he and do I need to get him his own tank :}

fuzzy looks like a decorator crab.

is the second one dead, cus i thought emerald crabs were green :D

thats a nice urchin

and welcome to AC!
 
Hi,
I took the emerald out. At first I thought he had just molted but..... no longer green.
Its strange this guy appears and is a bit bigger than emerald
Thanks for the welcome
 
with claws like that he may be a concern, he is kinda pretty tho. like a steamed stone crab. if you can get more pics that would help, but otherwise just wait for other peoples input
 
Found this guy as I was moving some rock around, any ideas. Preferably quickly, so if he's a nasty one, I still have a general idea where he's at.
Thanks as always,
Jason
