Sorry for bad pics

Caught this in the trinity river in Irving texas. The body is silver in color with a sucking mouth of sorts.

This fish was in a freshwater creek in kentucky it also has a really flathead thank you.

My neighbor caught this fish in our lake after 2 years of stocking tiger musky in the lake could this be one?
Let me know what you guys think!

my father and I went fishing at a lake filled with trout and caught this small baby fish we later put into our aquarium. You can see in the video "Fred" started eating the other fish and at some point we had to get rid of the whole aquarium because of him. I however don't know what he is - a trout?

Found in an inlet in quintana roo mexico, some sargeant majors were found close

While passing through Coeur D'alene Idaho we went for a walk around Riverstone Park and saw several of these cute little fish, I'd guesstimate 4 to 6 inches long. I didn't get great pictures, and google lens told me that it was anything from a whale to an aircraft carrier (I swear it's getting dumber as AI advances). I didn't see anything in the list of common fish in the area that looked very similar, but fish can look so different in different stages of life. Any ideas?
