Only reason I'd advise against a barnacle blenny (or more than one for that matter) is the fact of size, 2" is a large fish for a 5G, while the clown goby only gets to 1.5" if that.
Plus, I've seen barnacle blennies in my lfs
, they don't just sit in the barnacle, they're scanning/perching all around for food, only once they're scared do they retreat (and very fast I may add) to their barnacles
