Overview
Sunset Montipora (Montipora setosa) is a SPS coral in the family Acroporidae. Encrusting Monti with bristly raised polyps. Sunset Monti morph is a classic with red-orange polyps on green flesh.
Taxonomy
- Family: Acroporidae
- Genus: Montipora
- Scientific name: Montipora setosa
- Common synonyms: Setosa, Sunset Monti
Habitat
In the wild, Montipora setosa is reported from Indo-Pacific, where it occupies shallow reef flats and upper slopes (typically 1-15 m). The species adopts a encrusting 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: 3 months
Placement and lighting
- PAR (placement zone): 150-250 PAR
- Water flow: medium
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 setosa 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 0.4-0.9 cm/month. Propagation by fragmentation is straightforward for encrusting 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.
Propagating Montipora setosa
Overview
Montipora setosa is a species in the genus Montipora, family Acroporidae, grown in the hobby as an encrusting small polyp stony coral. According to Wikipedia, the genus exhibits submassive, laminar, foliaceous, encrusting, and branching growth morphologies, and colours across the genus span orange, brown, pink, green, blue, purple, yellow, grey, and tan. The Sunset designation refers to a color form of this encrusting species.
Reproductive Mode
Like other members of the genus, M. setosa is a hermaphroditic broadcast spawner, with spawning typically taking place in spring. Because the eggs already carry zooxanthellae, the symbionts are passed to the next generation by vertical transmission instead of being acquired from seawater. In captivity the coral is propagated almost entirely by fragmentation of the crust.
Fragging / Asexual Propagation
To frag an encrusting Montipora, a chip is cut off the crust, ideally with a thin layer of the underlying rock, and mounted to a plug. Under medium-high light and moderate flow the tissue spreads outward across the new substrate, re-establishing the crust. Encrusting Montipora are typically faster to heal and more forgiving of cutting than branching Acropora.
- Cut a chip from the encrusting crust with some rock attached.
- Glue the chip to a plug with living tissue uppermost.
- Position under medium-high light and moderate flow.
- Wait for the tissue to encrust the plug before relocating.
Common Challenges
As with all Montipora, the Montipora-eating nudibranch is the leading risk. An undescribed Phestilla species is reported in the literature to feed on the genus, while the described pest Phestilla subodiosus feeds specifically on Montipora and has become a commercial problem in aquaculture. Eggs concealed on the crust make eradication difficult.
