This little critter is the rough equivalent of the "Junkyard Dog" of Hanauma Bay. He's pugnacious, extremely aggressive and when he is 'in heat', these characteristics are amplified 100 fold! I've been attacked by this 3 inch critter on more than one occasion and quickly slip into my 'tactical withdrawal' mode! Oh yeah, he is called a 'Hawaiian Dacyllus' and is a member of the Damselfish family.
