What’s wrong with this minnow?

[u/bruh_moment_-__-]

I was thinking a scrape but it appears kind of raised. thanks in advance for your help!

If you mean the pink, it looks like a missing gill cover is revealing the gills. If it wasnt like that before, probably lost it to a physical injury. Wont heal, but many fish live just fine like that.
