That is extremely helpful. I am also a new corn owner and am worried because my 'Amber' is not eating, 'she' hasnt eaten since Feb.16th, and is also very active in 'her' tank. I've been putting mice in tank weekly but it just get pushed around. I have been watching 'her' like a hawk for signs of illness, dehydration, mites etc but 'she' still looks big and strong. 'Shes' just over a year old, 36" and looks like Bitsy's pic above. (never had him/her professionally sexed) SO now I'm thinking I have to change 'Ambers' name to 'Ember' my boy : )) I just got him a 75 gal tank with lots of things to climb on, he's having a blast. What you said makes total sense. Thanks!!
