On an average males will be between 12-13 feet but that is not a guarantee. They can and do get larger-feeding schedule as well as genetics (how big the parents were) plays an important role in how big they will get.

As far as him staying smaller b/c he is het green-NOT TRUE!!!!! The genetic color and pattern traits have no have bearing on size.

Also, if you are going to cut him back to feeding him every 10 days after he reaches 5 feet make sure you up the size of his prey item from the medium sized to a larger sized of whatever you are using as he will get hungry and those extra 3 days he may get a little grumpy adjusting to going longer without food.

He is a gorgeous burm!!!!!
