Acro crab moved

[DMBillies]

I have a white acro crab with a black stripe across it's face. This morning I noticed that he had moved off of the colony that I got him in (probably 4-5 months) and moved over to a neighboring acro. Both colonies look perfectly happy. I'm just wondering if that is common/normal or if I should take it as an indication of something.

The only 'acro' crabs I've had moved from pocillopora sp., so I don't think it's anything to worry about. He's just movin on up to the East side. You know, to one of those de lux apartments in the sky.
