i have a tank the 32"x13"x13" he just kept breaking out of the screen top i had small holes to run my temp and humidity gauge through but he pushed them open from like a 1/8th of a inch opening to a 4 inch wide hole. I would like to avoid a rack system just due to the fact it nice to have him on display in the side room. any suggestions on how to run cables into this type of cage because it looks like he's going back to his old one
