Hi im new here and do not own a tegu but plan on getting one from varnyard soon... I wanted to know how often do u guys replace the substrate and how often to u clean the whole enclosure or tank? Also what do you use to clean the tank and whats best way to clean it ? Mine is going to be housed inside a smaller tank from store whatever vanyard tells me to get and then i will either buy something much much bigger or build one with my friend.
