I just bought the fish less than a week ago from a pet store. It was in a tiny container, and then I moved it to my 1 gallon sized tank. I know it's better if the tank is bigger but tanks are expensive and I wouldn't have enough room in my dorm room. I've never owned a fish before, much less any animal, so I worry about my fish a lot.
The purple rocks are hermit crab gravel (which is anti ammonia), if that makes any difference. When I first bought the fish, the fins in the front (the reddest ones) were red, and the rest of the fish was blue, white, and purple. Then slowly I've noticed it develop the red on the fins and I'm starting to freak out. I've already changed the water once, and my friend told me that her fish is okay and she only changes the water once every 2 weeks, But I read online that when you have a smaller tank you have to change it more often.
I feed it 3 beta pellets a day and it's always enthusiastic to eat. and I would say it's moderately active, and it moves all around the fish tank, or stays in one spot (when it's sleeping, I guess?)
Could this color change be normal, or should I be worried? I checked the pH balance and it's at a normal range. I even used that water conditioner for my tap water, and even though I don't have a filter or heater, the temperature is in the 70s-80s where I live. At lowest it's in the 60s, but that's only at night, and my fish isn't near my window
I really hope I'm just overreacting, but if there are any problems, like ammonia poisoning, what could I do to fix it? Thanks so much, I'm already attached to my fish. If it died so quickly I don't know if I'd be able to have another fish again. Or do you think this fish is a goner and I should return my fish to the pet store? I have a 1 week store refund
Additional info, added Tuesday October 16 2012, 12:01 pm: Sometimes my fish jerks around, too. Like right now it kind of jerked and hit the rocks at the bottom a little.What is that, too? And is it bad that I do 95% water changes? I won't change so much again, the water had just gotten cloudy before (I think it's because I forgot to pre-wash the hermit crab gravel) and after the fish started getting red I thought it would be better if I just started all over again..

They often turn red, or bright colours as they mature or when comfortable. They sometimes even instantly change colour.
But if you are worried, take it to the store you bought it from for advice. They are of course trained.
But have a read, to make sure it's nothing serious. I googled "Betta fish colour change" and loads of websites popped up with useful information.
