Often they advise for basilisks, a male with 2 or 3 females, a terrarium size of 150x80x180 cm, the height is important as they like to climb. For a couple we have a terrarium of 160x60x110 cm, this size pleases us. They prefer a little pond, so they can drink, bath, swim and cool down. The ideal water temperature is 25-28 ºC. The temperature in the terrarium 28-30 ºC and some heath bulbs, so they can sunbathe. At these spots the temperature can increase to 40 ºC. At night the temperature may cool down until 20-25 ºC. The terrarium needs a high humidity, between 70-90%, at night this may increase until 100%. During the raining season you can sprinkle 2-3 times a day for a longer period, in the dry season 3-4 per week will do.
We have over almost the whole bottom a pond with running water through a cascade. This gives the terrarium a high humidity, so we do not sprinkle. We use an external filter. As the basilisks almost always shit in the water, we do not have to clean the terrarium that often.
