This is Joffrey. I adopted him several weeks ago after I seen his condition. (Lethargic, heavy breathing, red gills.) He is in a cycled (Just tested the water and did my weekly water change. 0 nitrites, 0 ammonia, and 20 nitrates is my parameters) He is in a 10 gallon tank heated at 78 degrees. I have noticed a bump on his side. You can see it in the picture. Am I doing something wrong? Or is it normal? There's also discoloration around his cute little face and his gills just look red and awful. Also, when he does flare, only one side of his beard flares up. I'm just so worried about him, and I want to better provide and take care of him if I am doing something wrong.
