BLUE TONGUE SKINKS

My juvenile Irian Jaya had a fecal gram stain done at the vet and the results seem point to some variety of Coccidia in his system. I attached the results from the lab. He was prescribed a .04 ml injection of Ceftazidime every 72 hours. If I am understanding everything correctly the Coccidia can re-infect the skink thru the poo so I need to set up some sort of quarantine tank and clean up every poo ASAP. What is the best and healthiest way to keep quarantine conditions and decent humidity without putting unnecessary stress on the skink?

Paper towels will work fine as a substrate and easy to change out. Your profile says you're in Florida so the humidity should be more than adequate for an IJ with a good misting from a spray bottle.
