Mine was close to 2' mark when it was killed only had it for like 1.5 years. Have pics from the people that produce them of some they have close to 3'. Since both the adults get to over 3' I'd say it's a safe bet that it would get between 3'-4' eventually. They don't seem to do well in aquariums according to others that have kept them. Mine was very hardy and had growth rate similar to a slower growing rtc or that of a fast growing tsn. Over 1' in less than 6 months from the 2.5" I bought him at. Slowed down a bit after that. An extreme appetite also. He would eat and his belly bulge would be gone by the next morning. Lends me to think they have a very high metabolism.
