I know its not the same, but my red blenny has loads of personality. Depending on what side of the tank I am on he will move over to that side, sit there and look, then dart into a rock, then come back out and look at me with a real Gary Coleman, "what you looking at" expression.
When I put my hand in there he will come up and bite me once, then just move around my arm playing. He even jumped into my cup once then back out into the tank!
He actually is the boss of the tank, despite there being an angel in there. He has no problem fighting the angel for food. Then again, my ocellaris clowns will also challenge the angel with no fear.
It's brilliant to watch. I'd say go for it.
