The Reason for me can be summed up in two words "Live YOung". Thought this is not with out it fair share of hardships, emeralds are far more difficult to begin breeding than chondros, but the egg thing is a pain in the ass. that and you better be ready to have a 6.5 foor emmmy dig its 1/4-1/2 inch teeth(all 4 of them) into your arm and chew arround for 10 sec. or you better go to chondroweb.com and chill with the eggheads(not in a bad way. All in all i feel the emerald is a far more interesting animal to keep, and is a creature which you will be passionate about keeping for a lifetime.

p.s. I have keep chondros as well, sorry to all the eggheads for the egghead comment.
