In august 1999 we bought 2 young Basciliscus plumifrons, almost 2 months old. Soon they became hand tame. After half a year it was clear we had 2 male basilisks. During the first year this was not a problem, they got a bigger terrarium, so they had all the space. But as they became adult, it was clear who was the dominant male. The dominant male was chasing regularly the other male. As we had a tropical greenhouse of 3 by 4 m, we thought, there they will have many spots to hide, probably this will be a good solution. Indeed, the tropical greenhouse was big enough for the both of them, the dominant male found straight away his favourite spot, his territory and the other male was not allowed to approach. But the other male had enough space to have his own territory, but he took care to stay out of sight of the dominant male.
The first week they came straight away to us when we entered the greenhouse, to look if we had brought food for them. But soon they became more shy. After a few months we had to get them out of the greenhouse, because they lost weight. Obviously the basilisks were too spoiled to get their food just beneath their noses and now they had to hunt by themselves. Unfortunately they did not succeed to obtain enough food. As we set out their nourishment and the basilisks were not fast enough to catch the crickets etc. straight away, they disappeared soon between the plants. Although we put lots of nourishment in the greenhouse, they had difficulty finding their ‘prey’.
