I think it was Greg Bryant from retic ranch that I talked to that told me he likes his breeder males to be on the smaller side. Around 45-65lbs. He said if there overfed then they will exceed 100lbs extremely easy. I'll probably wait a couple years till my anaconda gets full grown till I jump to a retic. I have a big enough room to put a 8x3 or 8x4 cage in.
