Symptoms and Treatment
How has your betta fish's appearance changed? The ends of his fins are a dark gray, and there is a chunk that's red at the end. You can't really tell unless you shine a flashlight on him, but it is all there.
How has your betta fish's behavior changed? He's perked up a lot since I brought him home about 5 days ago. He certainly doesn't act like anything is wrong.

Have you started treating your fish? If so, how? I haven't.
Does your fish have any history of being ill? No
How old is your fish (approximately)? No clue.
