Purple Milka Stylophora: A Beginner-Friendly SPS Showpiece

The Purple Milka Stylophora is a stunning small polyp stony (SPS) coral that brings rich violet tones and branching texture to reef aquariums. Its relatively forgiving nature, compared to many other SPS, makes it a fantastic choice for hobbyists who are ready to step up from soft corals and LPS.

Care Requirements for Purple Milka Stylophora

While this coral is considered hardy for an SPS, it still needs stable, clean conditions to thrive. Aim to keep your parameters as consistent as possible:

• Lighting: Moderate to high (PAR 150–250). LED, T5, or hybrid systems all work well.
• Flow: Moderate to strong, random flow. Avoid direct, blasting flow on the tissue.
• Temperature: 24–26°C (75–79°F)
• Salinity: 1.025–1.026 specific gravity
• Alkalinity: 8–9.5 dKH
• Calcium: 420–450 ppm
• Magnesium: 1300–1400 ppm

Stability is more important than chasing exact numbers. Sudden swings in alkalinity or temperature are the most common reasons this coral loses color or recedes.

Placement, Coloration, and Growth

The Purple Milka Stylophora develops thick, finger-like branches with a velvety purple surface and contrasting polyps. Proper placement will help it maintain that signature color and compact growth form.

• Tank Position: Mid to upper rockwork where it receives good light and flow.
• Space: Leave room around the colony for growth and to prevent stinging from aggressive neighbors.
• Color Maintenance: Stable nutrients (nitrate 5–15 ppm, phosphate 0.03–0.08 ppm) support rich coloration; ultra-low nutrients can cause paling.

As it grows, you can shape the colony by carefully trimming outer branches to encourage denser, bushier structure. Always use clean, coral-safe tools and handle the coral gently to avoid tissue damage.

Tips for Long-Term Success

Once established, this coral can become a centerpiece in mixed reefs and SPS-dominated systems. Keep it thriving with these practical tips:

• Acclimate to higher light slowly over 1–2 weeks to prevent bleaching.
• Provide random, turbulent flow using alternating powerhead programs.
• Test alkalinity at least twice per week until your consumption rate is known.
• Use an auto top-off system to keep salinity from drifting.
• Consider light broadcast feeding of fine coral foods once or twice weekly.

Pro tip: If you notice tips turning white while the rest of the coral looks healthy, it may be a sign of rapid growth and skeleton extension rather than tissue loss. Confirm by checking for strong polyp extension and stable parameters.

Building a Stylophora-Friendly Reef

The Purple Milka Stylophora pairs beautifully with other SPS such as Montipora and birdsnest corals, as well as peaceful LPS on lower rockwork.
