I don't know about you but I would. I have yet to see a vivarium that is too large. Of course you don't NEED larger vivs but they sure are nice for many reasons. If you really want to have fun, get into the 100+ gal. range and you can have something that starts to approach self feeding.beeswaxx said:I have a 15g right now, but I am contemplating selling it and getting a 29 or 33 gallon. Would I be happier with a larger tank?
