Mystery Fish from Utila Lower Lagoon

Picture 024.jpg

I was snorkeling in the channel between Deep Blue Resort and the lower lagoon trying to add a checkered puffer to my life list (which I got) when I saw this strange guy.  His pectoral fins were long and flexible kind of like gummy arms.  About 2-3 feet of water, 3-4 inches (7.5-10 cm) in length. Habitat brackish mangrove lagoon.  He ducked down in the silt after I took the shot.  Not the only strange and new fish I saw on this dive--but one I managed to get a pic of.  Very rich and diverse fish down here.

Crested Goby - Lophogobius cyprinoides

It looks like it might be a Crested Goby - Lophogobius cyprinoides. Page 283 of Reef Fish 3rde. Cool find, I've always wanted to see one of those.

Digitally enhanced version of the mystery fish of Utila

Here's a digitally enhanced version of the pic done by Steve Fox at Deep Blue Resort.

Louis, thanks for the comments.  It does look a lot like a goby, but I don't think it's a crested.  The color is wrong and the long ventral fins are unusual. You can see the pale spots more clearly in the enhanced version.

All the water on Earth is all the water there is.

I am pretty sure it is a Lophogobius- I can see the crest, it has the light-edged sort-of-ocellus on the first dorsal fin and they do sometimes get large.
