Can anyone identify this? It cam on an acro frag. It's tiny.

 

[Timbo13]

just found another one. What is it...

 

[Timbo13]

managed to get them out of the acros. here's better shots

 

[Timbo13]

one of them is a bandit crab - reefsafe
not sure about the pink one

I wanna say they're commensal as their pincers look to be blunt, but it's hard to say.
Bad crabs tend to have sharp claws for ripping stuff apart

For now i've let the bandit crab live in one of the acros. The pink one is just in a bucket for now till I can be sure it's safe.
Thanks Greg

I cant see your first 2 photos but the second two are definitely a acropora crab. They are beneficial to the coral.

Thanks. Glad I kept them.

Just found another when moving acro up higher in the tank. This one is really small and hiary. It seems fine as it was living the same acro as a different commensal crab. Is it really safe though. Anyone recognize it?
