I've been entertaining the idea of planting a few mangrove trees in the new tank, but am curious as to whether their roots need to be embedded in a mud substance or can simply be 'free' in the water column and have the plant be secured to rocks. Will the roots attach to the rock work?
Another side question. About how tall do these plants get? I know there are varying species. Do some stay significantly smaller, or do they all end up about the same?
