Around Wednesday/Thursday I noticed my red devil was covered in white spots. I figured it was ich so I bumped up the temp and added salt. Saturday morning I found him lying in the corner sometimes turning over a little but never completely on his side. Just to test how sick he was I tapped my finger on the front glass and he attacked it like normal. Most of the white spots were gone but there was still a good amount on him. I did a 50% water change and added salt back to his tank. This morning he is still in the same corner but he's tilted up (pic 2). He doesnt care to chase my figure and he looks like he's barely hanging on. A large majority of the white spots are gone but his skin looks odd (pic 3). The best way I could describe is it looks dry and flakey. I dont know what to do. Whenever I have dealt with ich it would have cleared up by now. I need help! This is one of my new favorite fish and its the first one my GF likes.
