Who is this little guy?

Maybe 2 inch long, at Blue Heron Bridge this Friday evening. My guess is, a baby batfish?

it is something from Blenniiformes - Wikipedia
exact family and genus i do not know, but it has something similar with Signal blenny (Emblemaria hypacanthus) but another colour. May be something from genus Emblemaria - Wikipedia.
