Sounds like a possibility, although I have a stand for both
aquariums, and was hoping to have one on top of the other while
taking up as little space as possible. I've recently contacted a
company that specializes in low-heat HO and VHO bulbs and ballasts
designed to provide natural light (or the next best thing) for reef
aquariums.
Time will tell. I am going to set up these terrariums in the spring,
but for now the planning gives me something to do while half my
collection is dormant.
