Fish ID please

Not sure what kind of saltwater fish is this,...

Looks like a young barred cardinal fish

This looks like a species of killifish or maybe pupfish. Where was it collected?

 

[Chasmodes]

The collection location will help identify this. I agree with Pbh-reef that it is a species of pupfish, perhaps a sheepshead minnow.
