Good morning everyone... To all who helped yesterday, thank you. I bought a heater and went home and did a 25% water change.I used the soda bottle to baffle the filter. Still no change, maybe even worst at 10:00pm. I did 50% water change and left him alone. This morning when I turned the light on he was laying on the bottom as he has been. After getting ready for work, I went to check on him and he was swimming. He's definitely better, but... His colors are still off and faded. He did interact with me a little and tried to eat but spit it out. When he swims, he looks bloated or just not natural, like he's forcing himself from side to side if that makes any sense. I'm going to watch him and keep an eye on his fins. I can't tell if his fins are clamped yet, but let's hope he continues to get better.
