How often do you feed your betta fish? He was being fed 2 times per day with a small bit of each food by my mom (I thought that was way too much). I've dropped it down to a small pinch of one or the other food a day, giving him a day or two break in between.

Symptoms and Treatment
How has your betta fish's appearance changed? His fins are ragged and splitting, his top fin is white and brownish and pretty much almost gone.

How has your betta fish's behavior changed? He's been staying at the top or bottom of the tank alot more then usual, but he still eats when I feed him, still swims around and acts happy, his fins are just droopy alot.
When did you start noticing the symptoms? About a week and a half ago.
Have you started treating your fish? If so, how? Started using the new water conditioners, have been doing full water changes ever 2-3 days. I finally got some API Fungus Cure and Maracyn 2 but I wasn't sure if you could put them both in a the same time so I only put in the API Fungus Cure at the moment.
Does your fish have any history of being ill? No.
How old is your fish (approximately)? I got him from Petco, but i've had him for about 5 months.
I've been reading and reading up on fin rot till i'm blue in the face. I haven't tried the AQ Salts yet because the guy at the pet store told me he didn't think a Betta Fish needed them. Apparently Bettas need alot of things they're not supposed to. I didn't think they needed a filter or a heater either, so I haven't been using those although I did get him a heater but it's a little small for his 2.5 gallon tank so I ended up not putting it in there. I've heard about cycling a tank but I didn't think i'd need to do that with 100 percent water changes every week. I'm looking into getting him a 5 gallon tank so I can put the heater in if he survives..which i'm seriously hoping he does because i'm going to be a wreck if not. He seems to be doing okay with the treatment so far, he's still swimming around and being active, but his fins aren't getting any better. Any help would be much appreciated!
