Thank you for the quick reply. The reason that I wanted the 4x2x2 was because we can get most of the materials for next to nothing and the small mesh screens would allow for minimal heat/humidity release. I'll keep in mind about the tubs though. I've seen people use them before, I just never thought of them as too appealing from his pov. The only other downside is i've already gotten him accustomed to having a tub as his feeding box. More recently he's gotten a little more eager when i feed him and strikes at my shadow as i walk by. I just don't know how well he'd adjust to having one be his new permanent home. But again, thank you for the insight and I'll definitely look into it.
