I just bought a fish(I literally bought him 30 min ago) who is doing absolutely terrible and I think he is going to die! He wasn't acting very healthy in the store but I bought him anyway and am very worried about him. He wasn't swimming around his bowel at all in the store but I didn't think anything of it.
He barely moves except to get air and I had to lower the water to 3 inches in the container I'm floating in my big aquarium(It's the warmest) so he can actually reach the surface.
He was very pale, and is still pale.
His fins look like they might have a tiny bit of fin rot on the tail, but I don't think it would effect his health this much, and they haven't grown in yet too (he's a halfmoon) and he seems under weight to me. He's not super small (Like an inch and a half long) so he should be able to eat food they give him, but maybe not....
His water looked bad in his bowel like they hadn't changed it in 3 or 4 days
His breathing is so shallow I can barely see his gills move
This shows the depth of the water, the container is at an angle so it's twice as deep in the back
When the water was deeper, after he struggled to get to the surface he would sink back down and land on his tail, the fall to the side :(
