Something is very obviously wrong

Good to hear.....you might add some soft or silk like plants or even a clean coffee mug to his tank. This will help make him feel secure..

I have a couple cups I could add, I just didn't know what materials I could put in and what I couldn't. (and more importantly which of the things I have are made of those materials)

Just an fyi, some fish don't tolerate the mid-80's very well. My female responds very badly to water warmer than 78 degrees, and lower than 74. She gets very pale and lethargic with cold water (this was before I knew better and hadn't given her a heater) and extremely lethargic with stress lines with warmer water (this was after I got the heater set to 76 and then told I should gradually warm it to 80 for optimum health). And during a water change, she does better if colder water is put in her tank, rather than warmer water.
Just a thought if he takes a turn for the worse again.
