So we have a little Sandboa...and most of the time he hides and sleeps during the day and in the evenings is sometimes active. But lately he's been cruising his tank more often. This morning he was crawling all over the tank and my daughter sat by him while she ate her breakfast. When she put her fingers up to the glass he struck at her (striked? Struck looks weird). Anyway, this is NOT typical behavior as sometimes he doesn't even strike at his food. I did just recently switch him from pinkies to fuzzies. his temps look good and I haven't changed anything that I've been doing. He's in sand since I'm highly allergic to Aspen and other plant matter, but he never gets fed in the sand. He just ate on Tuesday night. Any thoughts?
