As I was doing a water change this morning, I noticed my favorite girl had a kink in her spine. She still swims perfectly fine and has a great appetite. She's about 1-1/2 years old, and a petco fish, so super poor genetics. I don't expect her to live super long but I'm hoping to get at least another year out of her. Is there anything I can do for her? will I eventually have to euthanize her? Thanks in advance -Hania.
