Oh that poor thing!!!!!!!!!!!!!!!!! He needs a way bigger cage! If you don't end up keeping him because of housing for him- let me know. I'd take him in a second!
There's a company called glasscages.com who sell cages at the shows in Florida, BUT they also do drop offs in many Florida cities, too. You could see when the next time they'll be down is.
48x24x12 is $125, 48x24x24 is $165.
Then he needs a basking spot at about 105F, ambient temp 85-90 on the warm side. He needs a UVB light- either a fluorescent Reptisun 10.0- and it has to be that brand, or an MVB spot light, as well as full spectrum lighting.
How I have Isabel set up is with a full spectrum spot light and the Reptisun fluorescent.
Here's Isabel's viv: (Which is a 40 breeder and I am getting her a bigger viv- either a 4x2 glass or a Vision cage- undecided yet, but she's a couch potato. See her in the back under her hide?)
The spot light is a 100 watt full spectrum, and she has an 18" fluorescent Reptisun 10, which I place diagonally over her hide and branch. She has probed thermometers on her brick and in her hide.
Then when you get him, you should probably have the vet do a fecal to look for worms and coccidia. Many people think a very low count of coccidia is acceptable, but you don't want him to be overflowing with it. Treatment isn't bad- oral deworming and the coccidia treatment is oral Albon seven days on, seven days off, seven days on- recheck.
