What percentage of the water do you change when you perform a water change? Look up

Symptoms and Treatment
How has your betta fish's appearance changed? Turned dull/grey in color and has several grey blotches on his body that have started growing fungus. White fungus around the mouth.
How has your betta fish's behavior changed? Does not eat, barely swims, either rests on the bottom of the tank or floats at the top.
When did you start noticing the symptoms? When I got home last weekend. I left for two days, came back, and noticed his dramatic change.
Have you started treating your fish? If so, how? I believed it was finrot and basic mouth fungus, so I started treatment with melafix. Seemed to work for a little bit and suddenly just seems worse.
Does your fish have any history of being ill? Yes, I've had him a month and he has been sick the entire time I've owned him.
How old is your fish (approximately)? I don't know, I would guess a year or so?
