Mystery Acro Crab Good/Bad or just Ugly
 

Ok so this crab hung out on an Acro that is doing fine for about two months and has now moved to my new Tri colour.
It has white eyes but is orangey/brown and hairy.
Any thoughts on if he is good or bad?

If the coral looked fine over the course of two months, I'd wager the crab won't be a problem, really. I had a pencil eraser-sized Acropora sp. frag that was right outside a little hole a 1" crab lived in, and the frag is doing great, now closer to the size of a golf ball. Crab never touched it.

I would keep a close eye on him and real watch to see if he is eating stuff off the coral or the coral its self... generally good acro crabs seam to have smooth shells and the bad ones seam to have harry shells but like I said this is just a generalization so it could be either.

i've found some of those at the tip of a bbq stick :biggrin:

Bad, remove it asap... It is a polyp eater. I have had this exact crab

I agree with one divided, they eat polyps.
