Red Mangrove (Rhizophora mangle), characterized by their spider-like "prop roots" that stand out of the water, are very popular among aquarists for several reasons. The red mangrove adds a unique touch to any saltwater, freshwater or brackish aquarium/refugium. This adaptability is possible because the plant conserves fresh water by excreting salt through its leaves.
Propagules quickly take root in sand or mud. They’re also perfectly happy growing in gravel, live rock or water with no substrate at all. Just make sure that leaves are above the water, and the root system stays moist. Red Mangroves may even be planted in aquariums, containers or in outdoor ponds, provided they are not exposed to near freezing temperatures.
