What is the average length for a female(I've read things saying 3ft and I've read things saying 7ft)? Do they go through a color change like ETBs and GTPs do? Do they use all the vertical space or mainly hang out at the top? Do they have weak spines as babies like GTPs? Are they difficult to start feeding as babies? What about ATBxETB hybrids? I'd love to see some of yours to if you don't mind!
