Rhizophora mangle is characterized by its spider-like "prop roots" that stand out of the water and is very popular among aquarists.
They happily take root in sand, mud, gravel, larger rocks, or water with no substrate at all. Just make sure that leaves are above the water, and the root system stays moist.
Red Mangroves can thrive in fresh, brackish, or full seawater. This adaptability is possible because the plant conserves fresh water by excreting salt through its leaves.
