Rainbow Montipora

The Rainbow Montipora is a stunning and highly sought-after SPS (small-polyp stony) coral, named for its vibrant mix of red, orange, green, blue, and purple hues that shift depending on lighting and water conditions. This fast-growing encrusting or plating coral originates from the Indo-Pacific and is an excellent choice for experienced reef keepers looking to add a pop of color and texture to their tank.

Care Guide:

• Tank Size: Suitable for nano (20+ gallons) and larger reef tanks, though 50+ gallons is preferred for optimal growth and stability.
• Temperament: Peaceful – does not have sweeper tentacles but can grow aggressively, overtaking neighboring corals if not managed.
• Lighting: Moderate to high (PAR 200-350); best color development occurs under strong LED, T5, or metal halide lighting.
• Flow: Moderate to high – requires strong, indirect flow to keep detritus off and encourage proper growth.
• Placement: Best placed on mid to upper rockwork, allowing space for its plating or encrusting growth pattern.
• Feeding:
  • Primarily relies on photosynthesis via its zooxanthellae, but benefits from:
    • Occasional broadcast feeding with reef amino acids, phytoplankton, or powdered SPS coral foods.
• Water Parameters:
  • Temperature: 74-78°F (23-26°C)
  • pH: 8.1-8.4
  • Salinity: 1.024-1.026
  • Alkalinity: 8-12 dKH (stable levels are crucial)
  • Calcium: 400-450 ppm
  • Magnesium: 1250-1350 ppm
  • Nitrate & Phosphate: Low but detectable (NO₃: 5-10 ppm, PO₄: 0.02-0.07 ppm) – excessive nutrients can cause browning, while too little can cause starvation.
• Compatibility:
  • Peaceful coral, ideal for SPS-dominated tanks, but should be given room to grow as it can spread quickly.
  • Avoid placement near aggressive LPS corals (e.g., torches, hammers, galaxea) that may sting it.

Summary:

The Rainbow Montipora is a fast-growing, visually stunning SPS coral that thrives in strong lighting and stable reef conditions. With proper placement, high flow, and occasional feeding, it will develop intense rainbow coloration and create beautiful plating or encrusting structures, making it a standout addition to any SPS reef aquarium.
