On Friday I am getting a brand spanking new (well, new to me) tegu from Rodney at TegusOnly. To say I am excited would be understating it just a bit. However I have a few questions I hope someone can help me with. I am having a 8x4x4 enclosure built, but until it's done I have a choice between a 40 gallon breeder tank with the doors in the front and wider front to back, or a 55 gallon tank which is longer by about a foot. I have a 150 watt basking bulb, a reptisun 10 uvb fixture, a CHE, a cave, eco earth, a hygrometer, etc... pretty much everything except the bigger enclosure. My question is, which tank? If someone could give me some advice before Friday that would be greatly appreciated. Thanks!
