I know any animal you put time into will eventually become more used to you, but I'm asking which one by it's natural character is more likely to be a pet? There's a vast difference in natural character traits from an Asian Water monitor vs A Nile Monitor. I'm interested in determining which of those two species (Quince and Mertens') seems to show more of those asian water monitor like "pet" or "companionship" traits. If anyone has long experience with both of these any and all information would be appreciated thank you.
