I'm looking to create a large viv and trying to decide the best and most cost effective method for the tank. I want something front opening so it's either an exo terra or build my own. The larger exo terras are expensive and would still require some minor mods, but I'd be off the ground running much quicker. A custom setup would be great, if I can pull it off, but I'm not sure of costs. What would be an average cost to build your own tank, roughly 36Lx18Wx24H or maybe 36H? I just want info on the tank alone, no background/falsebottom/hood/stand. Roughly what could I expect to pay for the glass, silicone, and sliding glass door stuff? Thanks!
