Ok, first, read the caresheet. Get/make two identical hides that are very secure and closed in, just barely bigger than your snake can fit. Get a thermostat. (Reptitemp 500R is the cheapest, but will do in a pinch.) The UTH can reach 120* F and sometimes 140-150. It will burn your snake. A vet visit and treatment is more expensive than the thermostat, so get one! Put the thermostat probe on the UTH directly and use the thermometer to set it. Get a digital thermometer with a probe if you don't have one already. No one trusts the round gauges or mercury or stick-on things. There's an AccuRite that's usually at walmart or lowes or home depot etc. Keep the glass under the hot hide in the low 90s. 95 and up is unsafe. For the humidity, cover the screentop with something. A permanent solution is foil tape. The 'swimming' could be her trying to drown mites, so just look for those. They often hide in skin flaps like under her chin and in the vents. Drowned mites will float in the water.
<--I can't believe that exists.
