Largemouth bass

[islandboy1]

Hello my largemouth bass has a white outline on his back fin and I'm concerned because it hasn't gone away yet and I'm not sure if it's something to be concerned about or just something that may normally occur

Thanks

Nothing to be concerned about. Improve water quality, especially lowering nitrates by removing bioload (too much good bacteria)
Fungal infection is common and usually not serious.
Don't stress him out just do some more often WC's
