Symptoms and Treatment
How has your betta fish's appearance changed? He is very dull looking, his fins are ragged and very thin - almost transparent
How has your betta fish's behavior changed? Just today, he seems a little lethargic. Resting on the bottom.
When did you start noticing the symptoms? About a month ago I started noticing he wasn't as colorful... I figured I was imagining it until it got really bad... I feel terrible.
Have you started treating your fish? If so, how? Just put him in a 1-gal quarantine tank
Does your fish have any history of being ill? No
How old is your fish (approximately)? I don't know. I have had him for a month and he seems very young.

I'm worried sick about him. Milo showed the same symptoms before he died. I feel like a fish killer.
