How much and how often you do water changes for him?

Also i know you wrote that you did aquarium salt treatment for him but you never wrote how much of aquarium salt per gallon did you use?

Does his tail has ragged edges; getting shorter and shorter, falling apart; large parts of the tail just drop off; has white cottony like patches; fuzzy like patches; bloody tips; getting pale?

Bettas fins like that are very fragile.

Like Oldfishlady wrote it can be due to breeding , genetics, water movement, etc ,some larger finned males will have this problem chronically. Small homes with no water movement, no décor is the only way to keep this from happening.

You just need to watch and make sure there is no behavior changes or other symptoms that i described.

Keep his water super clean :)
