I found a spectacular looking hexagonal tank on Craigslist that I'm picking up tomorrow. It's 45 gallons, and initially I thought about putting a chameleon in it, but I also need a new house for a bunch of my cresteds. Since I have all females, I was wondering if it might make sense to put all my gals together in one big mega tank (figure that at least 4 adult geckos would live there). Then I read on a few sites that they might have trouble finding their food, and dealing with such a wide open space. Do you think a 45 gallon might be too large?
