Hi, I have tried to do as much research as possible but I need a little help.
So far I have got the vivarium (4ft by 2ft by 2ft), a repti-glo 10 UV light, caged basking lamp, and heat mat.
Question 1: I understand that the heat mat goes on the outer, under side of the viv. But at which end? The hot end, to boost heat, or the cool end to maintain cool spot temp?
Question 2: the major source of beardie controversy, choice of substrate. I understand that beardies may suffer from impaction if they ingest small particles eg sand. However, I would prefer to go with some form of calci sand, for looks, but also because the reputable reptile shop where I’m getting all my stuff from use claci-grit (slightly larger grain size) in their baby beardie tanks, and claim that impaction is rare. Also they suggest that any grit that is swallowed will dissolve; this is the claim made on the substrate packaging.
However, many people on various websites swear they would never use sand, or even calci-sand. I am confused. I want to make the right decision for my prospective pets. I would hate to cause them harm or distress.
Any help/opinions would be much appreciated. Thank you.
