Hawaiian Sunset Monti Care Guide

Hawaiian Sunset Monti (Montipora digitata var. 'Hawaiian Sunset') is a SPS coral. Care covers 150-250 PAR, medium-high flow, reef parameters and feeding; beginner level.

Overview

Hawaiian Sunset Monti (Montipora digitata var. 'Hawaiian Sunset') is a SPS coral in the family Acroporidae. ORA-bred designer with bright orange branches and blue polyps. Reliable beginner SPS morph.

Taxonomy

Family: Acroporidae
Genus: Montipora
Scientific name: Montipora digitata var. 'Hawaiian Sunset'
Common synonyms: Hawaiian Sunset

Habitat

This morph of Montipora digitata var. 'Hawaiian Sunset' is propagated exclusively in aquaculture and is not sourced from wild reefs. The parent species naturally occupies shallow reef flats and upper slopes (typically 1-15 m) and grows in a branching form, which the aquacultured fragments retain in the home reef.

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: 3 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 digitata var. 'Hawaiian Sunset' 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: beginner. Reported skeletal growth in well-tuned reef tanks is approximately 0.7-1.5 cm/month. Propagation by fragmentation is straightforward for branching 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.
