I have two fish (I'm pretty sure they're females) which I'm worried about. I know, as it's spring, it's breeding season, so they're getting fatter with eggs. The only problem is, they're also leaning as they swim, and they spend a lot of time just hovering in the water. I've recently moved them into a new tank, but I don't think they're still upset because of that, they seem fine. Do you think it's swim bladder, or is it normal for breeding season? Please help!
