this could be a good thread
this is the only one of my viv that i have. its a 30gallon tank that had fish in it. i used the fish tank hood (for the flouresent fixture) and the cutout for the fish tank filter acts as a vent then i have my blacklight heat bulb directly inside the tank (they cant get any closer than 7'' from it) because with it outside of the tank it was too cold in there. and their basking lamp comes from the back side and they lay on the back side of that fake log
i know my set up is kinda plain and basic but it works for now, when i get some cash i will turn the whole stand that the tank is in, into an enclosure. i might sell the 55g fish tank and make another enclosure up there for when i have to seperate the 2 babies
