I was thinking this is a Knightia but now I’m not so sure. The body shape seems wrong and it does not appear to be compressed. @Fossildude19 @RJB

I believe it's a Knightia. 

The lack of pectoral fins 1/3 of the way up the body, lack of a long anal fin, and lack of thicker support bones in the post cranial hump tells me it isn't a Diplomystus. 

The fact that this is also about 5 inches in length puts it at a Knightia size range, and rules out Gosiuteichthys  and Erismatopterus.

Lack of a second dorsal rules out Mioplosus.

Maybe there was a nice looking lady fish nearby. It looks as if he was sucking in his gut.

Thanks for the confirmation Tim. I needed a gut check before I stuck this in the “big box o Knightias” I’m putting together for a client.

Happy to help, Kris.  

I have a small 2.5 incher that is quite similar looking.
