Has anyone done this in a tank indoors. I have a friend who has a six foot mangrove tree in a large outdoor tank around 250 gallons. I want to try it inside and in a much smaller tank like a 29gallon i know this sound small but my plans are to keep it well pruned and trained like a bonsai coming out of a tank. I figured I would use a sand substrate with some amout of live rock for filtration. I really dont plan on keeping many fish maybe a goby or something along those lines if i go full salt or a mono or two.
