Mangroves are aquatic trees or shrubs that grow in the coastal waters of the world's tropical oceans. These "rainforests by the sea" prevent erosion and house a diverse population of indigenous animals.
Red Mangroves (Rhizophora mangle), characterized by their spider-like "prop roots" that stand out of the water, are very popular among aquarists for several reasons.
Simple, Varied Planting Options
Red Mangroves arrive as 6"-8" candlelike tubers, which 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.
Tolerance to Several Degrees of Salinity
Red Mangroves can thrive in fresh, brackish, or full seawater (although they cannot be moved freely between water of varying salinity). This adaptability is possible because the plant conserves fresh water by excreting salt through its leaves.
Affinity for Bright Light and Warmth
Red Mangroves thrive under
metal halide lighting, fluorescent lighting, or even placement next to a large, bright window. They also require
temperatures above 60°F (which is typical of most indoor home aquariums). Red Mangroves may even be planted in outdoor ponds, provided they are not exposed to nearfreezing temperatures.
||Intertidal Waters of Tropical Oceans.
||Brackish to full Seawater. Sand or mud substrate. Leaves must be above water.
||72-78°F; sg 1.020-1.025; pH 8.1-8.4; KH 8-12
||Seeds or a Propagule.
Keep aquarium water at 72-78°F, with a pH of 8.1-8.4, and dKH of 8-12.
Remove fallen leaves before they can decay and raise nutrient levels.
Red Mangroves can grow substantial root systems, and become very tall.
Choose a large aquarium or pot to prevent stress from frequent replanting.
Trim the plant's growth tip to prevent excessive height, and avoid aquariums
with tops or canopies.
Mist Mangroves with purified water or wipe excess salt from the leaves
with water daily.
Regularly add trace elements and an iron supplement.
