I bought a male betta fish named Peeta a week and a half ago. When I bought him he looked perfectly healthy except when it was feeding time. He would not swim up to eat and when the pellets sank he would eat them and spit them back out. I finally got him to eat after 5 days, but the next day I had to leave for vacation. He was left in the care of my best friend who, until now, has taken pretty good care of my other betta and my cat. She has had 3 bettas herself and has two 60 gallon tanks of guppies. I figures I could trust her. I couldn't be more wrong. She never fed anyone (my two bettas, my brother's betta, and my cat) for 4 days. She literally came in once to feed and she put WAY too many pellets in (about 15). He (obviously) didn't touch the food, and when I came back he was laying at the bottom not moving. I quarantined him in his original jar, fearing he would die (I'm moving him to a 1/2 gallon) and again, he laid on his side, not moving or eating. He started breathing rapidly and looked like he was in pain (don't ask, I could just tell) I checked him for everything, and the only thing I could think of were he was cold (fixed that, still no improvement) or swim bladder.(he looks like he can't swim up) Just a few minutes ago, he was swimming around but now hes laying on his side breathing heavily. He still hasn't eaten and I'm really worried about him... What do you think is wrong, and what can I do to help him?
