But the species has an average adult size of around 3ft. They can stay smaller and brighter like younger animals with husbandry less condusive to growth, this is why in the wild they take so long to become sexually mature.
Of course anyone who does not understand how a monitor grows normally or matures with whats available probably will not see reproduction.
The pictures look like any old bosc you can buy thousands of from wholesalers at about $1-$2 each. They vary by where they originate, darker animals from cooler or higher altitude areas.
Bright orange, red, brown, gray, black, bluish, and many other colors are completely normal.
Ive had more than a few "dwarf" sized and "small genetics" monitors of a few species over the years that mysteriously grew to double their size in a few months in my care but never grew to adult size or close to it in their former owners care, why is that??
