You mean mud carp, right? It's almost the same as a white strip, but the body (from belly to back) is wider than a white strip, and the dorsal fin and caudal fin are also longer than a white strip. Body shape is between white stripes and crucian carp.

White stripes are hard to grow (half a catty to a catty, but hard to see), but the mud carp can grow bigger.

There is a kind of canned "Douchi shad", and the fish in that picture is soil shad.

The answer is not easy, hope to adopt, thank you!

Here is a picture of mud carp.
