So I recently got this snake from a friend, its a albino burmese python, supposedly its 6 years old..but its only 6 feet long, I'm pretty experinced with a bunch of snakes but this is my first burmese. So I'm wondering if there's a way to tell a age of it? Or is there a way to tell the diffrence between a dwarf or regular. The snake isn't starved or anything either the girth of it is normal for one its size, but he said he fed it 2 weeks or so,

Most likely it was not fed appropriately by who ever was caring for it. Snakes grow the most in their first year of life with growth slowing drastically by the end of the third year (though they continue to grow their entire lives). If the snake was not fed properly then it was environmentally dwarfed.

dwarf burmese python are very rare and expensive so i think youd know that its a dwarf. could be that he didnt feed it enough. i know you said it looked fat enough for its size but it isnt big enough for its age.

Feeding a snake enough food when it is young and the size of the enclosure
