I want to get a tower rack system to keep several mole salamanders and maybe some others ie. mandarain, etc. I wanted to know if the mole salamanders really need light. I don't want to shine a light directly on the rack given that it is plastic. I figure that since these salamaders typically like wet, cool, and moist conditions, shining a hot lamp over them would not be wise anyway. In addition, they mostly stay underground anyway. Can anyone verify this and tell me what I should do differently for the mandarains and other salamanders like a tiger and fire. ThANKS!
