Notes

The most delicate and trickiest basilisk species, hard to breed, and nothing for beginners. Very shy, with a high humidity and water requirement; it defecates in the water → frequent cleaning. Rarely kept, and German-language husbandry data are thin (some figures are derived from English specialist sources).
