Aries, my red/white veiltail male, has some torn and ragged dorsal and tail fins. The tips of all of his healthy fins are bright white, which is how I figured that something is wrong with the dorsal and tail fins. His dark red color makes it very difficult for me to tell if the ragged tips of his ill fins are bloody or just torn. He does have a history of illness, see below. Given that fact, I want to make sure that since he's recovered from his last bout of illness, I want to get his fins treated and back to normal as soon as possible so he doesn't become septic. His tank decorations include silk plants and standard gravel. I opted away from the plastic plants since they can more easily tear fins, but I don't know if the silk plants he has are exacerbating his problem since he had already torn fins when he came home. I've reduced the number of plants to two relatively short ones so he hopefully won't catch on them while he heals.

Symptoms and Treatment
How has your betta fish's appearance changed? ragged dorsal fin, half to 3/4 of the way towards his body in long strips, tail fin starting to look a little ragged
How has your betta fish's behavior changed? None, still eats like a pig and zips around the tank.
When did you start noticing the symptoms? Came home from the pet store torn like this about 3 months ago,
Have you started treating your fish? If so, how? Started approx. 1 gal water changes daily to make sure that ammonia/nitrates/nitrites and dangerous bacterial levels don't get too high to impede healing.
Does your fish have any history of being ill? Also had major fungal infection, constipation, bloating, and broken side fins when he came home. The side fins have since regrown completely, no bloat or fungal infection anymore, is not lethargic like he was when he came home. His other post-pet store symptoms have long since disappeared, but his dorsal and tail fin have stagnated or begun to look ragged.
How old is your fish (approximately)? Post-pet store 3 months, I don't know how old he was when I bought him aside from an adult.
