From what I have read, the GTP is much easier to care for. ETB's are more expensive, have more exacting care requirements, and have regurgitation problems. You might require stitches if an ETB bit you, they have largest teeth of any nonvenomous snake (proportionally). A GTP has more color variation, is a little less pricey, and in my opinion, more beautiful overall. this might be a bit biased, as the green tree python is my favorite snake. If you are serious about the GTP, i would purchase greg maxwells 'The more complete chondro'... it's quite expensive for a hard copy, but it is not that expensive if you choose to get it on your nook or kindle![]()
