Soon I'll be moving to a new city (new temporary job in between semesters) and I'll be taking my little one with me. She is currently in a 1.5ft wide x 4 ft long x 19in tall tank right now. The thing weighs about 150 pounds and isn't the most mobile thing. She uses about 30-40% of the tank (warm side). She is NEVER on the cool side. What is the absolute smallest tank size for a full grown dragon? I take her out quite often and let her bask under a mercury vapor bulb so she wouldn't be pent up all day. Thanks everyone!
