Stylophora Milka.

About Stylophora Milka

Stylophora Milka (Stylophora milka) is a small-polyp stony (SPS) coral - skeletal, reef-building, light-demanding, and at the deeper end of the husbandry difficulty curve. The species sits within a recognized hobby category and is sold both as wild-collected specimens (where legal) and as aquacultured frags from coral farms like ORA, Tidal Gardens, World Wide Corals, Battle Corals, and Jason Fox Signature Corals.

SPS health is binary in a way LPS and softies are not - the coral is either growing and coloring up, or it is in decline. There is no middle ground. The water chemistry, light, and flow you provide either match its requirements or they do not, and the response time is fast: tissue recession (RTN, rapid tissue necrosis) can take a colony from healthy to dead in 48 hours when parameters swing.

Reef parameters and chemistry

The Stylophora Milka requires the parameters that all SPS-dominant or mixed reef tanks target. The numbers below are the husbandry floor - hitting these consistently is more important than hitting them perfectly.

• Temperature: 76-80°F
• Specific gravity: 1.025-1.026
• Alkalinity: 7.5-9.5 dKH (consistency matters more than the absolute number; pick a target and hold within 0.3 dKH)
• Calcium: 420-450 ppm
• Magnesium: 1300-1450 ppm
• Nitrate: 1-10 ppm (ULNS systems run lower; some color is lost at <1 ppm)
• Phosphate: 0.03-0.10 ppm (zero phosphate stunts growth and pales colors)

For SPS specifically, alkalinity stability is the single most important variable. A swing of 1+ dKH in a 24-hour window will trigger STN (slow tissue necrosis) on sensitive specimens. Drip dosing or a calcium reactor with consistent output is mandatory once you have more than three or four colonies.

Lighting (PAR and spectrum)

Stylophora Milka requires moderate to high PAR - target 200-350 micromoles at the colony. Spectrum should be heavy in 420-460nm royal blue with supplementing 380nm violet and modest white channels. AI Hydra, Radion XR15/30, and similar reef-spec LEDs all work; T5 or hybrid T5+LED systems excel at penetration into deeper SPS-dominant tanks. Photoperiod should be 8-10 hours of full output with 30-minute ramp-up and ramp-down on either end. Avoid running peak intensity for more than 6 hours - longer photoperiods produce more algae growth than coral growth.

Flow and placement

Stylophora Milka demands moderate to high flow - 20-40x turnover routed across the colony rather than directly at it. Direct laminar flow on SPS tissue produces flow-burned bare patches. Use multiple powerheads (Maxspect Gyre, EcoTech VorTech, Tunze Stream) on alternating schedules to create the turbulent, chaotic flow that mimics reef hydrodynamics.

Placement in the tank

Place SPS in the upper third of the tank where light intensity is highest and flow is strongest. Bottom placement of SPS is a common beginner mistake - it produces pale, brown-out colonies even when chemistry is on point. Frags should be placed and not moved - SPS responds to placement changes by retracting tissue, and serial moves compound stress.

Feeding

SPS is photoautotrophic - it derives most energy from photosynthesis via its zooxanthellae symbionts. Direct feeding is supplementary at best. That said, broadcast feeding amino acids, oyster feast, or reef roids 2-3 times per week measurably accelerates growth and color development. Target-feeding with a basting bulb works for accent corals; broadcast feeding works for whole-tank dosing.

Fragging

SPS frags propagate from healthy colony tips. Use a Dremel with a diamond cutting wheel or a coral bone-saw with a flush guard. Cut just below the branching point, mount the frag with reef-safe cyanoacrylate gel on a frag plug or rubble, and place in a low-flow, moderate-light location for 2-3 weeks until the cut site encrusts and tissue grows over the wound. Aquacultured Fast Aquatics vendors typically frag from established mother colonies aged 6-18 months.
