Hi all,
new here have just set up a small nano reef 80L over the last few months and have spotted today a new crab which must have come in on a coral.
if any one knows what it is please let me know is it, whether it is friendly or not , how big will it get or any links to information on it will be greatly appreciated

Thanks in advance for any replies see photo attached for crab its about 10mm across light brown and very furry

Guessing here that its a common hairy crab (wonder how it got that name!!)

Havent found out wether good or bad yet tho

I would normally suggest its best to sump them, they can get a bit big and might start munching things you dont want them to
