Thanks, I visited the web site of Twin Oaks, a vendor that supports the GCCA. Their web site is www.glasscages.com. They have some odd sizes that sound interesting, including half-hieght 3, 5 & 10 gallon tanks. I'm assembling an 8 foot rack that's 2 feet deep. An 18 inch deep tank with a low hieght sounds ideal.
