I had an idea last night after reading about mangroves in reef tank refugiums etc... and ended up perusing some pics of Mangrove Bonsai. Mangroves actually grow faster in freshwater than salt.
So the thought was to have a freshwater display tank with a Mangrove tree growing out of the tank. Pruned to keep it small.
Some obvious issues; Time. It would take a long time for the mangrove to look like a real gnarled old tree perched on a mound in a swamp(decades perhaps).
Also the light would have to be pretty high over the tank which would effect the par level getting to the substrate. Although this could work out to not be an issue. Since Mangroves like high light you might end up with a good selection of plants that would work in the resultant med/low light in the actual tank?
Anyone tried something like this?
