Thanks for reaching out about Coco and including pictures. Swellings on one side of the body are often an indication of an internal mass. That could be a intestinal blockage, displaced swim bladder or an enlarged organ. Check water quality and correct any concerns. A veterinarian should be contacted for possible treatments, but also contacting the person/business you purchased her from would also be a good idea. This isn't much you can do for these problems at home. Good luck.
