is that in inch's? Im not sure about that tank because i donno wut type of unit your useing lol but i know a size that generally is considered minimal for a adult is a 40 breeder which is 36"x18"x16", and what most people use for there beardies is somewhere around 4' long and 2' wide (or a 75 gallon tank which is 4'x21"x18)", this way when there full grown they can still turn around in the tank with ease. So if what you have is above what the 40 breeder is then you should be good! :mrgreen: And please if any of my points are wrong someone correct me Thanks! :wink:
