Crab Hitchhicker on Acropora

[erndog1001]

Got a ORA Acropora frag the other day. last night while I was feeding I noticed a very tiny (say 1/8-1/4") fully formed crab. Its so tiny I had to view it thru a magnifying glass to be sure of what I was looking at.
Its appears to be pure white in color. Its not bothering the coral. just curious if anybody else has seen such a thing?

Is it an acro crab?

 

[Calappidae]

Sounds like a harmless white acro crab.. actually VERY benefical!

Just google some images of them to be sure.
