Looks good. He's got alot of places to hide and wedge into. He will be more active for awhile until he settles in and figures out there is no way out and that is his den. As for the tape thing. Ive never had a problem taping wire for years but you do need to be sure its good tape and the glass is very clean. I would not use that frosted scotch tape because that stuff doesnt stick very well. With no chance of it peeling up anywhere. If it ever starts to do that you just replace it.

Looks very good so far. Believe me they like very small places. You wont need the bigger tank for at least a year or so depending on how fast he grows.
