Very Very VERY cool. Those guys remind me of the lawnmower blennies I've had in my reef tanks (except the blennies don't do so well out of the water).
Good luck keeping them - maybe make an online journal detailing your experiences keeping them. I am sure there's plenty info out there on them - it's just that this is the first time I've seen someone on an online-fish-nerd-forum post about them.
Again, VERY cool.
If you have any friends, relatives, or co-workers who think that evolution is poppy-cock, have them over for an adult beverage of choice and set 'em straight!
