I have a guppy who appears to be paralyzed from the "waist" down. She can't move her caudal fin at all. Infact her what used to be fanned out tail is now solidly formed into a sharp point. Also, her lower body doesn't even move, just kinda drags behind her. I thought she was just dieing.
Well she's still alive and she's been living like this for about a week now. She usually stays on the bottom and, from what I've seen, can't seem to swim very high. She swims using only her pectoral fins. All other fins are angled sharply into a point. But with her pectoral fins, she swims all over the place. And she still eats well.
Is there something I can do for her? What caused or is causing her condition? All the other fish are just fine. This is happening to only her.
