Probably a dumb question but fires scare me - how do you keep your tanks with under tank heaters??? Right now my Hognose is on "blocks" to allow airflow, but I want to move him out of my old office and into either my new one or the house proper ... I'm scared to not have him on the lifts - how safe are the UTH's??? #hognose #undertankheater #axanthic #conda #teenyboi #runt
