When my WTF, Martha, is out of quarantine I would like to get her a Medium-tall Exo-Terra, 24”W x 18”D x 24”H (would this be big enough for two WTFs?) The thing is this, the chest of drawers I'm planning on placing this on is 15 1/2" deep, so the tank would hang over a bit front and back. Is that ok or should I get a board to put down on top of the chest first that will fit the base of the tank? I don't want the tank cracking or being compromised in any way
