I have a little orange and black Sword Tail who lives in an aquarium with a Silver Dollar fish. I was doing a water change and I saw that the sword tail is actually missing the sword part of his tail. So he is basically just left with a ripped tail as of right now. But not only that. He also has some sort of growth on either side of his body, where his tail meets his body. Its on both sides of him and it's pretty big. It makes him swim all wiggly. This part of his body is black and the growth is also black. He's still swimming around and eating but he's not swimming as fast as he did before. I've done all the chemical testing and cleaned the (proper sized) tank and everything. So if anyone can help me and my Bo out here I'd really appreciate it.
