Identify your North American Native Fish

[guppy]

Nope, not a Coregonus.
There were 4 members of this genus, 3 of which were only found in California, one of those is now extinct. This is the largest of them.

Tui Chub Gila bicolor ?

Chiselmouth (Acrocheilus alutaceus)

 

[guppy]

Nope and nope, does it help to say it gets almost 18" long.

 

[guppy]

No more guesses, I'll give it another hour or so then post a new one.

 

[guppy]

All right, that was the Sacremento splittail (Pogonichthys macrolepidotus)
This next one comes with 2 clues, it is less than 2 inches long, and it is found in only a small area of a single state.
