Okay, so Nibbler ripped his fin a couple of months ago, and I posted on here. Everyone just said to wait for it to heal, and give him salt baths. I've been doing that for two months! It's not helping at all. I actually came back from camping today, and his tail's even WORSE now! One other thing, he's so fat now! I feed him JUST as much now as I did when he was normal, and he wasn't fat, because he always swam around. NOW, he just sits on his butt all day, because it's hard for him to swim. He only comes up for air and food. He's not losing weight by swimming now, and my brother said he fed him the proper amount. I feed Nibbler JUST as much as I feed Flame, and Nibbler's actually a tiny bit bigger then Flame, and Flame's stomach is a normal size, because Flame swims around. I don't want to starve Nibbler, and I want him to swim like he used to, and I want his tail to be better. Time and salt baths AREN'T healing him, so can I try anything else?
