Now that I have time, this is how my Paleosuchus are housed when indoors.
Air temps vary anywhere from 75 up to the low 90s for the indoor animals, so the critters can thermoregulate. The basking spot helps well with this as the temps cool off the further away the animal is from the spot and if you have a large enough enclosure.
The basking bulb is usually around 95-100.
When they go off feed, it's usually random things that set them off like changing the enclosure around, or just looking at them funny. When I notice they are not eating I just ignore them when it comes to feeding and after about a month to a month in a half, I'll
toss in a live something and it usually sparks them into eating.
I had a none eating Trig that wouldn't touch anything since the day I got it. Stayed off feed for about 4 months until I introduced a duckling into it's pond.. I removed it because it was kinda cute bumping into the wall and stuff, but after that, the animal has never refused a food item and is actually one of my best feeders, so try enticing the animal into hunting instead of just offering food.
As for your temps, Do not raise them any higher, make sure you have a temperature gradient in your enclosure, and yeah, the raise in temps could have got your animal eating. A good way to find out would be to set your old temps back up and see if the animal stops eating. Always nice to find out the source of something..
