Tail Injury or Rot?

Hello all, new here to the puffer forum and puffer keeping, long time aquarist.

Water parameters: pH: 8.5, Ammonia 0, Nitrite 0, Nitrates currently 5, (though I test weekly and change water when it hits 20), specific gravity 1.008 (using seachem marine salt)

Tank: 55gal, No tankmates. Crushed aragonite substrate. Hardscaped with Seriryu stone, some anubias and marimo balls,

Feeding: 2-3 times daily since he's a juvenile. Diet of bloodworms and bladder (pond) / ramshorn snails.

Water change schedule: Weekly to bi-weekly. I test parameters at least once a week and do a ~30% change once nitrates hit 20.

Only tank changes were re-arranged rocks and added a few more anubias. Aquarium has been set up since September. Squishy was adopted in late December after tank was cycled.

I got my green spotted puffer in December. Around mid-january i noticed a little nick in his tail fin. It didn't look like fin rot and he was otherwise healthy, active, always hungry, and displayed no signs of stress. Figured it might've just been a nip from whenever I got him since he was housed with a few other juvenile puffers. The wound seems like its gotten a little worse since the last 2 months. Not sure if I need to do anything? He still seems happy and otherwise healthy. My best guess is bacterial infection, but Im wondering what you guys think. Picture attached. The nick is small, but it looks worse when his tail fans out. He wouldn't sit still to let me get a better shot...
