Overview
Orange Cap Montipora (Montipora capricornis var. 'Orange') is a SPS coral in the family Acroporidae. Bright orange-red plating Monti with pink polyps. Classic reef centerpiece.
Taxonomy
- Family: Acroporidae
- Genus: Montipora
- Scientific name: Montipora capricornis var. 'Orange'
- Common synonyms: Orange Cap, Sunset Cap
Habitat
In the wild, Montipora capricornis var. 'Orange' is reported from Indo-Pacific, where it occupies shallow reef flats and upper slopes (typically 1-15 m). The species adopts a plating growth form on hard substrate within zooxanthellate reef communities.
Tank requirements
- Salinity (specific gravity): 1.025-1.026
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- Carbonate hardness (dKH): 7.5-9
- Calcium: 420-450 ppm
- Magnesium: 1300-1400 ppm
- Phosphate (max): 0.05 ppm
- Nitrate (max): 10 ppm
- Minimum system age: 6 months
Placement and lighting
- PAR (placement zone): 150-250 PAR
- Water flow: medium-high
Place this SPS coral on the upper rockwork where light is bright and water movement is strong, ideally turbulent rather than laminar. Acclimate gradually to high PAR over 2-3 weeks to avoid bleaching. SPS demand a mature system: stable alkalinity, calcium, and magnesium with phosphate and nitrate kept ultra-low.
Feeding
Montipora capricornis var. 'Orange' hosts symbiotic zooxanthellae and derives most of its energy through photosynthesis. Additional feeding is generally not required when lighting is adequate.
Compatibility
This coral is passive toward neighbours. Reef-safe with most fish and invertebrates.
Care notes
Difficulty level: intermediate. Reported skeletal growth in well-tuned reef tanks is approximately 0.5-1.2 cm/month. Propagation by fragmentation is straightforward for plating colonies — separate branches or polyps with a bone cutter, glue to plug, allow 1-2 weeks for healing. Maintain stable alkalinity (avoid swings above ±0.5 dKH per day) to preserve tissue health.
Orange Montipora capricornis: Propagation Guide
Overview
The orange Montipora capricornis is a color morph of Montipora capricornis, a plating small-polyp stony coral of the family Acroporidae. The species forms flat, plating colonies that expand by adding to their foundations and spreading outward, and comes in color variations including red, green and orange. Like all M. capricornis it occupies the top half of the reef where photosynthesis can occur.
Reproductive Mode
Montipora reproduces both sexually and asexually. Because the orange coloration is a morph, only asexual fragmentation preserves it; each frag is a clone of the parent. Sexual reproduction follows the broadcast-spawning pattern of the family Acroporidae.
Fragging / Asexual Propagation
- Pick a brightly colored plate with active growth along the rim.
- Cut the plate into chips with a band saw, tile nippers or a cutting tool.
- Glue each chip flat to a plug or rock with cyanoacrylate.
- Return the frags to medium-high light and flow to encrust and resume plating; the morph's color is retained in the clones.
Conditions for Propagation
As an upper-reef species, M. capricornis needs bright light and moderate to strong flow. Stable water with regular calcium and alkalinity dosing helps cut margins heal quickly and keeps the orange coloration strong.
Sexual Reproduction
Within the family Acroporidae, reproduction occurs by broadcast spawning, with colonies releasing gametes into the water column for external fertilisation and larval settlement. Captive spawning is uncommon, so fragmentation is the standard way to multiply this morph.
