I saved a fish from a pet store back in November. He's much healthier now and is a fun little guy. I came back from a weekend away and noticed he looked a little more hunched on his back than normal so I went back in my camera roll to find some comparison pictures That's from around December/January This is today. Is it possible for the deformity to get worse? I have no intentions on breeding but I want to make sure he's not uncomfortable or in pain. Swims good, eats good and is a total derp. Any help?
