This is my Betta, and he had been batting some fin rot since the late summer/early fall. He was getting better after summer and then all of a sudden, he started getting it back worse and was lethargic and floating strangely, when I finally realized, it was because the tank was too cold and he was stressed. Fast forward to two weeks ago, the heater is in and he’s healed nicely, but all of a sudden these pale marks/scales show up on his face and head this week.
He likes to sit against the filter tube and between the plant and stuff himself under the heater between the rocks, so I’m thinking these might be slight injuries, but I’m not sure. They are not fuzzy or raised, it just looks like discolored scales.
Any opinions would be greatly appreciated, thanks!

Thank you for posting
• Tank size: 1 gallon
• Heater and filter? (yes/no): yes and yes
• Tank temperature: 79-81 degrees
• Parameters in numbers and how you got them. Key water parameters include the amount of ammonia, nitrites, nitrates, and pH.: last time I checked everything was in acceptable boundaries.
• How long have you had the tank? How long have you had your fish?: I’ve had the tank and fish since spring of this year.
• How often are water changes? How much do you take out per change? What is your process?: normally, 50% change every two weeks. When dealing with fin rot, at least 15-20% daily.
• Any tankmates? If so, please list with how many of each: No
• What do you feed and how much: Pellets, twice daily, one or two. Bloodworms maybe once weekly or every other week
• Decorations and plants in the tank: Glass rocks, fake tree/plant
This looks bacterial. It could be graphite disease given the sudden onset. It is a genetic predisposition and is, I’m sorry to say, almost always fatal.
What you can try is treating with a broad spectrum antibiotic in food and only in the food. This link sums up different ways nicely.
