ROFL...
So, someone else digs on Jawfish as well...
The blue spot ones are cool, but spendy. IMO, the best one (I own two) is the Bali Tiger one. It has a black head, and yellow vertical bars on its body. A similar species is the black-cap. If you dont care about color so much, and you have the space, the dusky gets a bit larger, but is alot cooler personality-wise. They are perhaps the most... er... well... its hard to describe... like I said before... 'pit bull'. They eyeball you all day long if they can, and come out of their hole to 'punk you' here and there until you stick your hand in the tank.
