The biggest one I've ever had was a rescue female. She was 4500 gr (1500 gr BIGGER then Jag!!!). She was kept in a 10 gallon tank with a small water dish and a heat lamp on top. No hide. She took up the entire space all curled up. It was sad.
Despite all that, she was actually quite healthy. And unbeknownst to me, gravid. Found her on eggs one morning, now that was a surprise !! She only had 6 eggs (one went bad) but they were huge eggs. I remember that the largest hatchling was 116 gr and the smallest 89 gr, out of the eggs.
Jag really IS quite big around. Sometimes when I look at the pictures I think they make him look smaller then he really is, LOL. I know he is no "retic/burm" or giant of that sort, but man, he IS really strong. When he wraps to hold on or to try to move around my body, he can squeeze hard!!
