Well, since I got to see that cute little bugger you bought I thought I would help you out. Their care is actually very simple and they can live a very long time if not stressed. They are prone to behaving rather spastic their whole lives so they really are showcase animals not show off animals
It's best to provide a live planted terrarium, vines work the best and keep the humidity around 75-85%. Mist morning and night. They require a shallow 3-4"(1" for babies) deep, but large water basin as they love to swim and bath. They eat anything you put in front of them, size related of course and as adults can take pinkies no problem. Some also really enjoy sweet fruits like mango, papaya. guava, banana, strawberries and raspberries. UV light is essential, about 8-12 hours a day, with a temperature between 80 and 90 degrees. Night time drop of 5 degrees or so. They will climb and bask under a 75 watt heat lamp(mess covered to prvent burns) so provide plenty of sturdy branches and a few large hiding areas. Hope this helps, I'm just going by experience here but the one we have now(banded basilisk-same care requirements) is 14 years old
Take care,
