    Closest species I have found so far is Malacoctenus costaricanus but the coloration is not right. I have not been able to get a hold of Humann's Panamic book, is it in there?

    The few online images I have seen for M costaricanus seem to be a weaker match than M. margaritae. If you look at the images of margaritae, notice the white dot pattern across the face/between the eyes. A perfect match. Morphology a perfect match as well.

    Most fish that sit on the bottom are able to change color to match surroundings, so color is often less dependable as sturcture, and underlying patterns/markings.

    I do not have the Humann book either.

    I am sure it is Malacoctenus ebisui- they are known for having the darker tail-end that looks a bit like a triplefin (Enneanectes).

    Let me put it this way...
    I wouldn't ever claim to be able to make a definitive species-level ID from that photo :)
    I'd be willing to bet it's either a Margarita Blennie or a fairly close relative... Fishgod Blennie's definitely a possibility, or (gasp!) possibly a hybrid?
    Oh, and another thing... if any of y'all haven't noticed yet, there are at least three or two misidentified fish pictures floating around the internet, even on some seemingly reputable sites :D
