If your ammonia is 0.5 then that's your problem

+1 and it's a safe assumption that if you have ammonia in the tank you also have nitrites. What is the nitrite reading? Have you made any changes recently? new filter, removed anything, added anything? Something that might be causing a minicycle

Water temp is 80, ammonia 0.5ppm, nitrate 5 ppm, I'm going to lower the temp a bit. He's still sluggish just sitting on the bottom. I have him quarantined in a part of the tank as he was being picked on by my umbee. Doesn't seem to be gasping at all, I'm not sure what's going on with him. Have the other filter up and running since yesterday. He's only about 3 years old.

I agree with the ammonia being too high. I'd do a water change probably about 50 percent. Add a water conditioner like seachem prime it's a miracle worker. I'm sure you'll have some nitrite in the tank if ammonia is high. Nitrate isn't harmful to the fish but nitrite is the killer.
