I'm gonna hijack jake's thread a bit, but yeah, 6' tank. All plumbing is going to be completely buried. The plumbing across the top is for the 6' drip wall. On the right is a mini ficus stump and the left will be a much larger version, which will have a "puddle" in the void. I'm going for a true rainforest floor look. Ferns, aroids and vines.
