Lol, Finnick and I were doing so well. After his tail becoming increasingly worse while at the dorm, and then healing once I brought him home, I have not brought him back to the dorm yet. The bad news is that I can't watch him from day to day.
He has ripped his caudal fin, which is no big deal to me, although I think he has chewed on the top of his rip. The kicker, though, is his dorsal fin. It seems to have become weaker, almost thinner, and now it is torn. I can't tell if the current has just torn the weak tissue or if it's fin rot. Because of the way it is torn I don't think it's from his environment. When I look at them at just the right angle in the light, they have the barest clear edge.
He is also now missing scales on the top of his head. Note that he scavenges for food on the bottom of the tank, and he has a house he likes to swim though. I know this has developed over the past two days.

Symptoms and Treatment
How has your betta fish's appearance changed? There was a rip in his caudal fin, and I think he munched on the top part of the rip. His dorsal fin, however, seems to be become weaker and thin, and is now torn. Missing scales on top of head.
How has your betta fish's behavior changed? No changes, although he seems to be staying closer to the front of the tank.
When did you start noticing the symptoms? The caudal rip happened two weeks ago, the munching last week. The dorsal seems to have been slowly building over time, but no obvious signs of fin rot.
Have you started treating your fish? If so, how? Not yet, but I will do a large water change and perhaps add some AQ salt. Depending on the responses I may entice my parents to do water changes while I am at school.
Does your fish have any history of being ill? We fought with fin rot/tail biting (I don't know if we ever decided which) last fall.
How old is your fish (approximately)? No idea
I'm sorry these pics will probably be so big.
