Partially pigmented

  

This afternoon I was helping Eric look for a few invertebrates in Bodega Harbor for his class when he called me over to look at a small fish.  It was only ~3 cm (a little over one inch) long.

The fins were only partially pigmented, which made the fish look "rough around the edges" and very much like a little piece of kelp:

 

 

 

Here's a closer view of the fins:

 

 

 

 

And one of the tail:

 

 

 

We're wondering if this could be a juvenile kelpfish, possibly a Crevice Kelpfish (Gibbonsia montereyensis)?  If you have any thoughts about the identification of this fish, we'd be interested!
