Hi I have a 6 year old Female Jack Dempsey who has recently developed a solid black colour on half her body (see pic). She has had this discoloration for approx 3 weeks. But now in the last couple days is showing signs of budged eyes, bloating n laboured breathing. We have moved her into a hospital tank and could use some expert advise as to what this is. Ive never seen anything like it. Plz see pics.
