Hello! My lovely halfmoon (not sure what color), d'Artagnan, has been suffering from massive tail rot and fin loss for weeks. It's been slowly going away (almost a month now) and hasn't reach his body yet, but he's lost at least 1-1.5cm of fins.
Should I start medicating him? It's frustrating treating his fins rot for so long when a lot of people write online that it's a very treatable disease. :(
Any help will be greatly appreciated! I would love to see his fins grow back so he can swim in his full glory again!

Symptoms and Treatment
How has your betta fish's appearance changed?
Fins with red tips; fraying usually occurs near red tips (ammonia burns?). No black or brown ends where the fins rot. His fins started to get a wrinkled look too. They used to be smooth before.
How has your betta fish's behavior changed?
When did you start noticing the symptoms?
The day after I moved him out of his 2.5gal into a new (uncycled) 10 gallon tank with the AquaClear 50. His fins were torn to shreds and tips were bloody. I have a feeling the filter was too strong and ripped off his fins. Also, the tank was not completely cycled, so the tank may have been experiencing ammonia or nitrite spikes. He was usually eager to eat, even during Betta Revive medications. Now it takes him a little extra longer to figure out his food is floating (possibly from the live plants blocking his view). He's still eating eagerly. He used to flare normally. Since I moved his 2.5 gal back home with me (used to be at my boyfriend's), he started flaring a lot. Sometimes around two minutes or so. It seemed like a long time. Maybe he was stressed? He sleeps on the gravel instead of on the leaves or my plants.. possibly because he doesn't have any available hiding places? When he swims, I can't tell if he's swimming erratically or just excited. He swims back and forth in the front of the tank a lot. Very sociable and is always curious and swims around the front of the tank whenever he sees people nearby. He's been starting to lay on the tank bottom more often now, but it's more noticeable when he's trying to sleep at night. He seems normal for the most part, minus the erratic swimming. It's like he thinks something's after him. I'm not sure, but he might be tail biting. I think I saw him slowly creep up on his tail and try to bite it, but does tail biting come with red bloody tips? Or is the red tip from ammonia burn due to the exposed fin?
Have you started treating your fish? If so, how?
Yes, for a few weeks now. I moved him to a quarantine tank (0.25 gal) right after I noticed his fin rot. Treated him with Betta Revive for 2 days, but read varying articles so I switched him to an aquarium salt regimen and put him back in his old 2.5 gal to make him feel happy. His fin tips became red again after a couple days and the previous tattered fins completely fell off. Since the salt didn't work, I put him back on the Betta Revive in the 0.25 gal quarantine tank for a week. It's been over a week and his fins have been getting red at the tips on and off. It seems like I've been treating him for almost a month now.
Does your fish have any history of being ill?
No. Cardinal Tetras were added to the 10 gallon tank after I changed the filter to an AquaClear 20. Three of them died, probably from poor acclimation, but the tank not fully cycled might also be a culprit.
How old is your fish (approximately)?
Had him around 2 months, but he seems fully grown.
In the pics above and below, I noticed this more in white bettas. Is it normal to see that red line? Is it a vein or artery? It's also visible on his body next to the base of his caudal fin.
