Recently I’ve started to look for a tank upgrade for my bearded dragon. He is currently in a 40 gallon, and he’s about a year old. I have 54 inches of space in length and a maximum of 18 inches depth that I can use, and I’m looking for something that costs no more than $350, but I’ll go a little higher if need be. I would make one myself and have it fit to the dimensions of the dresser I have him on, but I have no idea where I’d even start. Not too sure about gallon equivalents either. I’ve heard that a 48” tank is 100 gallons in one place, and 65 gallons in another. Any help is appreciated.
