How can a 100g tokay gecko grow to a 300g?

The tokay geckos that you see online with the flabby skin weighing in at 375G!! are the ones that the people of Indonesia and malyasia breed. These geckos are OVERWEIGHT! A healthy plump male over the age of 2 should be right in around 70-100Grams. a Female will get that big aswell, but usually tend to be a little smaller - 60-80Grams is perfect. 300Grams isn't meaning yours is un healthy, it means theirs is heavy.
