I am extremely happy to report that Jasper has recovered from his case of ich. However, I think he may have a case of velvet, but I'm not sure. His color is fading from a solid red to a sort of "rainbowish"/metallic sort of red. In addition, if I shine a flashlight on him, it looks like he has a goldish sort of dust on him. But other than the loss of coloration, he exhibits no other symptoms of velvet. No darting, flashing, or scratching. I have the medicine to treat him, but am not sure if I should use it, because I'm not sure if he actually has velvet or not. Any advice?
