A little more specific question, there are Multiple species endemic to Madagascar.
Depending on which one, there may be some similar traits between them and Tokay. Madagascar is an area with a lot of humidity and relatively hot temperatures. With humidity levels reaching 65-85% daily and temps reaching up to 85-100F on a typical day, the Tokay gecko may be able to live in this area. One species of day gecko that come from Madagascar named the Giant Day Gecko are able to reach moderately large sizes, similar to a Tokay. Their is also species from Madagascar that have sticky pads (setae) on the bottom of their feet that allow them to scale almost and type of surface, as does the Tokay
Tokay geckos are native to North Eastern Asia. Including: Vietnam, Malyasia, Indonesia.
* Leopard geckos * Crested Geckos * White Lined Geckos (Skunk Geckos) * Fat-Tailed Geckos * House Geckos * Tokay Geckos * Golden Geckos * Madagascar Ground Geckos * Day Geckos
The Chinese water dragons cannot live with the Tokay geckos because they will feast on them.
Tokay geckos are known to be the "pitbull" of the gecko family. They tend to be very territorial and aggressive, although can be hand tamed.
No, Tokay Geckos may be more violent but Bearded Dragons are bigger.
Tokay geckos do not show the hemiphorical bulges like leopard geckos or cresteds. males have pores (as do all male geckos but they usually have a bulge) that are lining their "vents" these pores are where the male anatomy is contained. Pores are darker coloured spots along the geckos vent.
It's a Hoax..
A tokay geckos natural instinct is to defend one's self. A tokay will bark to ward off predators, call a mate, stress, or simple exhaustion.
Tokay geckos are one of the most aggressive gecko species. They're often reffered as the pitbull of the gecko world. These animals do not enjoy handling. Your presence is enough to startle this species.
Some can be tamed, maybe if you got it young enough. But short answer, no. Tokay's are notorious for being rather nasty tempered.
This is some reasons a leopard geckos and Madagascar day geckos can't live together: #1: Madagascars have a different environment than leopard geckos. Madagascar day geckos live in tropical conditions and leopard geckos live in desert conditions. #2 they would be fighting because they are territorial.
I would only keep one Tokay per tank, especially a male. They can be highly territorial.
