Ok so back to this boa thing. Iv noticed whenever the lights are off, he starts going up the side of his tank, his head and about 4-6 inches after the head, and he will just stay there. I started thinking stargazing, but like I said, it only happens when the lights are out, never in the daytime. Iv taken him out, looked him over, body seems nice and strong. He's been eating regular and pooing and peeing. I just don't understand why he's doing this up the wall thing at night. If I open his tank while hes doing this, he usually comes down, not like he's stuck there or anything. I just want to know what otter ppl think about this. I'll try get a pic of him next time I notice him doing this. Thanks everyone!!!
