Theres no way to tell for sure unless you know where the parrent orriginated from. I would say a B.c.Imperatror for sure. I was thinking Nic. or Honduran when the pic first came up. Most petstores are clueless as to what an animal is and its size potential. Most B.c.i. will reach atleast 5' over a period of years if fed enough food and some will even reach 8'+(rare and usually obese). I'll be looking forward to some updates on how hes growing as well
