Bix is a great eater and he usually poops a few days after feeding, 4 at the most I think. He ate 9 days ago and I haven't seen anything in his tank. His climate is stable, same as always, 88ish on the hot, 82 in the middle, 77 on the cool with a water temp of 70-72. His tank is in my room - zero foot traffic and I'm never in there either, also no change in behavior, so I know it's not stress. He was ready to eat last night but wore himself out trying to eat tail-first. Hopefully I'll come home to a poo tonight but if I don't, 9 days isn't normal is it?? He's 8 months old. Should I feed him despite that? I know he's hungry..if he's blocked up or something (?) is there anything I can do that won't stress him out too much?
