Hi!
Well things got bad, but now things are better. After writing the above post the little guy was basically floating lifeless all the time, stopped basking ,etc. I removed him from the large tank and placed him into a ten gallon hospital tank.
I raised his water temp to 80 degrees constant. His basking site is also up around 95, with a side spot that is around 84 in case he doesn't want the heat. But basically I wanted to get him up at 80 all the time.
So anyways, literally 12 hours or less after sitting in this nice warm water, in a smaller more private tank the little fella perked up BIG TIME!
He has started eating again with a huge appetite, basking, etc. I am going to be keeping him in this hospital tank for about a month most likely just to be on the safe side.
