I wanted to get started this weekend on making a burrow for my future mantis....but had a couple concerns. I know it has to have an entrance and an exit, but what shape should I make it? Also, Do you think it is likely that I will go through this big PITA effort of rescaping my Nano for his burrow, to have him not use it and make his own? IS there anything special I should take into consideration.....something that people commonly miss?
