Looking at tanks I also found one that was a "tall"...taller than its width. I am not planning on making a vivarium...not until I have enough room and talk to a few others who have set up a tank for Dendros. I want my mail foncus to be on the orchids. I like the flipping that tank on its side idea...it would alow for use of a neat pieve of root driftwood chunk that's perched on the top of the nearby dam...not if I could only find a way to lasso the thing to shore....I don't mind that idea of playing coyboy to get a coveted piece of driftwood...god, listen to me....I'm becoming a driftwood cowboy!
