I have one and I am in the middle of setting up a refugium for my 120 gal tank. I plan on putting him in the 'fuge temporarily. Seeing as the refugium is only 20 gal I am not sure if he'll be happy in there. If he appears happy then I will keep him, but if he doesn't seem happy then I will have to part with him. Seeing as this whole refugium set-up process has come at a time when I am setting up my new 120 gal tank, it may take a couple of weeks before I know whether I am selling him or not. If you don't find the blenny you are looking for within' a week or two, then PM me and I will let you know what my plans are for the blenny. The lawnmower blenny is great b/c they like to eat the microalgae off of the aquarium glass and they have a cool personality.
