He used to have a snail with him but I have since moved it
He has some hardscape and a live plant (not sure of the type)

The best treatment for fin rot is cleaning the tank up and maybe adding a bit of salt. If the fish was unwell before you got it, then just do a big daily water change and gravel clean the substrate for a couple of weeks and that should allow the fish's immune system to heal the damage.

You can also add a bit of salt (sodium chloride). Use 1 heaped tablespoon per 20 litres (5 gallons) of water. If there's no improvement after a few days, you can increase it to 2 heaped tablespoons of salt per 20 litres of water.
Keep the salt in the tank for at least 2 weeks but no longer than 4 weeks.

Why move the snail? Was it making too many babies?
Pics please, i can identify all of the common aquarium plants ：）
Perhaps the plant or hardscape is harming him

I moved the snail because my betta simply did not like him LMAO
He would swim up to it and flare which I think was adding some extra stress he didn’t need
I gave the snail to my female betta who doesn’t even realize there’s a snail in there
And I can attach a picture for you, ignore the cringey castle I am currently trying to find some drift woody type of deco for him.
side note: the LED is white I don’t know why it was snowing that color
