This blenny is by far my favorite that I've ever had, and perhaps my favorite fish. It beats out the bicolor, and the lawnmower easily. This guy spent the first night hidden under a rock ledge, but two days later he was just as curious about me as I was about him. I have a feeling that his is a teenager because he is losing his juvi colors and getting his final adult pattern. My LFS made up some name for him, but after some research I think he may be a linear blenny. In the past 2 days he has taken to spirulina tablets and mysis shrimp, if they float in front of his face. He spends a lot of time resting his head on some palys just watching me as I try and keep my fish room clean. BTW, if you know what type of blenny this is please let me know.
