I got my first betta on Wednesday. I thought it might have ammonia poisoning, so I changed the water yesterday and twice today because it looked to be gasping for air. Now it's standing on its head (head down at the bottom, mouth gasping, tail at the top, fins spread out) and I have no idea what it's doing. I am a first time fish owner, and none of the websites I've found are much of a help. Please help. Thanks.
EDIT- Now he's swimming around, but his smaller fins are moving rapidly and he can't seem to stay at the top of the tank for extended periods of time. Also, he pulled the standing on his head stunt again, except the tail section started going sideways. He's gonna die, isn't he?
DOUBLE EDIT- He is not shimmying along the bottom, and along with the fact he hasn't eaten much, I don't think it's swim bladder.
TRIPLE EDIT- He just went to the top, took a breath, and seemed to literally slide downwards head first. He is still gasping for air.
FYI-
-> Using tap water w/ water conditioner. Put water through Brita filter before I changed it the last time.
-> He has only eaten once that I've seen.
-> Water has been set out overnight and is at room temp.
->He is near a window, and getting indirect sunlight.

It is very warm in my room and he is near a window.
HE HAS ONLY EATEN ONCE.
What if I fast him, but don't do the deshelled pea? Will he still be sick?
