Montipora Sunset

Montipora Sunset: A Standout SPS Coral for Your Reef Tank

The Montipora Sunset is a vibrant small polyp stony (SPS) coral that can quickly become the visual highlight of your reef aquarium. With its glowing orange base and contrasting green polyps, this coral adds intense color and texture to both mixed reefs and dedicated SPS systems.

Montipora Sunset Care Requirements

Like most Montipora species, Montipora Sunset is considered moderately challenging. It rewards stable, well-maintained systems with fast growth and bold coloration.

Lighting

Montipora Sunset prefers moderate to high lighting, typically in the 150–250 PAR range. Too little light can cause dull colors, while excessive light may lead to bleaching.

  • Start in moderate light and slowly move higher if colors appear washed out.
  • Use a quality LED, T5, or hybrid system with a strong blue spectrum.
  • Acclimate to new lighting over 1–2 weeks to avoid stress.

Flow and Placement

This coral thrives in moderate to strong, turbulent flow. Good water movement helps keep detritus off the surface and promotes healthy polyp extension.

  • Place Montipora Sunset on rockwork where it can encrust and spread.
  • Avoid direct laminar flow from powerheads; aim for random, alternating currents.
  • Leave space around it, as it can grow quickly and overshadow slower corals.

Water Parameters and Nutrition

Stable water chemistry is crucial for Montipora Sunset. Sudden swings in alkalinity or nutrients are a common cause of tissue loss in SPS corals.

  • Temperature: 24–26°C (75–78°F)
  • Salinity: 1.025–1.026 specific gravity
  • Alkalinity: 8–9.5 dKH
  • Calcium: 420–450 ppm
  • Magnesium: 1300–1400 ppm
  • Nitrates: 2–10 ppm
  • Phosphates: 0.03–0.08 ppm

Montipora Sunset relies heavily on photosynthesis but also benefits from a lightly fed system:

  • Maintain low, not zero, nutrients for rich coloration.
  • Feed the tank with fine particulate coral foods 1–2 times per week.
  • Use an efficient protein skimmer to keep the water clean yet nutrient balanced.

Growth, Coloration, and Common Issues

Under good conditions, Montipora Sunset will rapidly encrust rock and create a bright, plating surface. Its signature orange base and neon green polyps are most intense under strong blue lighting.

Tip: If you notice the base turning pale or brown, check PAR levels, nutrients, and alkalinity stability first.

  • Fading colors: Often caused by ultra-low nutrients or too much white light.
  • Tissue recession: Commonly linked to swings in alkalinity or temperature.
  • Pests: Regularly inspect for Montipora-eating nudibranchs and consider a coral dip before introduction.
