a good article on mangroves.

imo, if you want to use mangroves as filtration, you're going to have to use quite a few. not really worth it in that regard imo, especially when you have a large diversity of macroalgae to pick from. However, they do make great little "bonsais" as mentioned and do attract some attention from visitors as a little odd tidbit. rather slow growers, but to prune just treat it the same as any other plant. nip off the apical bud and it will grow sideways.
they will survive in pretty much any light you give it, the more the better. I have a seedling in an empty HOB aquaclear with a piece of rubble. Im just letting the roots take hold of the rock so when i put it in the display proper (has to be tall enough to stick out of the water some), i have an anchor... that's the plan anyways
