I just bought my Betta fish on Tuesday, and it is Thursday now. When I bought him he was ALL bright blue with a light spot on his head that was kind light purple-ish. I bought him because he was the only one with a dirty tub, it had a lot of poop, and he had barley enough water to cover his body and I wanted to give him a good home. I talked to the sales person at Petsmart for about an hour to make sure that I had everything I needed to keep him. She told me that I did not need much space, or a heater, or a filter, and that all I had to do was fill the tank up with bottled water. So I ended up just buying a Betta starting kit, since I have gotten him I have changes the water once. His tank is not that big, but he does have room to swim around just fine, the box doesn't say how much it is but it holds three water bottles.... The kit came with gravel and a fake plant, which I put into his tank along with a fake turtle to keep him company (I didn't want him to get lonely)
But the problem is that he wont eat. I feed him the Betta pellets, and he has maybe eaten two since I got him. I feed him three pellets twice a day, but I skipped feeding him yesterday to see that if I skipped feeding him maybe he would eat, I just feed him and he didn't budge. He doesn't swim, he just floats there staring, and he looks so sad. Also he gets scared easily and jolts around his tank really fast for a second or two. On top of all of that he has lost all of his color and is a white-ish light-purple-ish, and he is starting to loose color in his fins too I think. I can not get him to flair up, he will start and then just stop and go back to just floating there....
I don't know what I did, I am hoping that maybe it is the tank temp and I can just buy a heater and he will be ohkay because I don't have a heater now. But I don't understand why he got so sick if that is the reason because I know a lot of people who have Bettas and they keep them in those tiny tiny bowls with no heater, and their fish are fine.
Please help, I love him and I don't want him to die, I don't know what I did wrong and I want to fix it :'[
