OMG good hitchhiker.
that is a emerald crab, part of the CUC that will eat algae, made popular for eating bubble algae
 
Excellent! that makes a change :) haven't seen any bubble algae yet so hopefully I won't! I take it this one is a youngster and will get the emerald green colourations it ages?
 
they get to about 2 inch and as they grow, so should their colour
 
Yeh looks like an emerald crab but it's hard to tell from the photo's. Here's the emerald crab care page for info

Not all mithrax crabs will turn green like the emerald. There are also a few other colors, I've seen both red ("ruby" crab) and brown ones. I have heard about blue ones as well, but have never seen one myself.
 
:hi: to the salty side of the forum - how about sharing your tank and a bit about yourself, us salties are a nosey lot :rolleyes:

Hi Seffie, will do! just about to go to work but I'll get some pics up soon :nod:
 
There is also black mithrax crabs I believe.
 
OK! Just managed to sort out some pics for you all :hey: I decided in Feb this year to transform my 95l cube into a marine tank after doing some hefty research! I have kept freshwater fish for many years but have always wanted to venture into marines and after seeing all your lovely tanks I couldn't resist anymore! :hyper: here are the pics:

The tank as it is today has a new purple rock of star polyps a couple more mushies and a Yellow watchman goby that I have called Moby :fun: the yellow polyps have moved to the back of the tank they have attached on some live rock so I cannot move them to the front :grr:

This was on my star polyps last night appeared to be a slow moving brown spiky slug of some sort ???? care to id anyone? the Peppermints made short work of it though so hope it was a baddie!

And last but not least Moby the Goby he was kept in appalling conditions in the lfs being attacked by another fish with no where to hide he was underweight and had much of his dorsal and part of his back bitten off unsure of attackers id looked like a white angel fish with a black stripe :angry: he is slowly getting better though :)
