Does your tank have a filter? No, he freaks out if there is any type of water movement.
Does your tank have an air stone or other type of aeration? No
Is your tank heated? No, but, after reading on here, I need to get him one, eh? He has a very, very bright light that I shine over his bowl, but I don't know if that really helps.
What tank mates does your betta fish live with? Do plants count? haha, none.
What type of food do you feed your betta fish? Bio-gold Betta Pellets

Symptoms and Treatment
How has your betta fish's appearance changed? Not really, but his top and bottom fin looks torn and the two fins that hang down have a little black on them. ALSO his fins look a little..wrinkly? it's not much, but I noticed it. The top fin isn't really torn, its more like there's a little hole in it.
How has your betta fish's behavior changed? It hasn't.
When did you start noticing the symptoms? Yesterday.
Have you started treating your fish? If so, how? Only by changing the water.
Does your fish have any history of being ill? Besides his SBD, he's been fine :)
How old is your fish (approximately)? Ehh... I got him in August, and he has grown MUCH larger since then, so like, I don't know..6 months? Maybe?
I'm just concerned about his fins, is it finrot? Fin loss? He doesn't have anything in his bowl other than a few anubias and a moss ball.
