This is an emergency. I got my fish Ferris on tuesday (it's friday now) from petco on an impulse buy. I've had bettas before, so I was expecting the usual.
He hasn't eaten at all since I bought him, and I've tried four different types of food. Last night he was acting sluggish, and he was laying on his side at the bottom of the tank for a few minutes. He was fine after that!
Today I noticed he has a bloated belly. I moved him to a smaller setup (not MUCH smaller) which has a light above it, and then about 15 minutes later I noticed he was acting weird- breathing heavily, almost like constantly flaring, and he will only stay at the top of the tank.. he only went to the bottom once when i accidentally scared him. I tried calling petco, and they said give him a pea. i did, no luck.
He still won't eat. PLEASE I want him to live.
