What is this fish called? Caught it fishing from shore.

Spotted Bay Bass? https://mexfish.com/fish/spbaybass/spbaybass.htm

Baby pinto

Barred Serrano

Largemouth Blenny.

Great sources for identifying fish in Sea of Cortez include:
Gulf of California Fishwatcher's Guide
Reef Fishes of the Sea of Cortez
A Field Guide to Coastal Fishes from Alaska to California (not exclusive to Sea of Cortez)

NOT spotted bay bass. We catch tons of spotted bay bass around Lobos and they look just like the Mexfish picture. Do not have the redness this one has nor the same fins.

Close, but I think the number of dorsal fin's before the "flag" is wrong.https://mexfish.com/fish/fgcab/fgcab.htm

Thank you everyone for their input on this fish that I have never caught before and to me I'm going with pinefish and the largemouth blenny.

The folks at www.mexfish.com have created www.mexican-fish.com that has a ton more info.
