Bowerbanki Coral Care Guide – Care, Feeding & Lighting Tips

Introduction

Bowerbanki corals (Acanthastrea bowerbanki) are a standout LPS coral known for their bold coloration, fleshy appearance, and unique skeletal structure. Sometimes mistaken for acans, they are a separate species within the Mussidae family and thrive under moderate reef conditions. Their vibrant polyps expand fully during the day, adding both texture and movement to reef tanks.

Scientific Name & Identification

Bowerbanki corals belong to the genus Acanthastrea and are characterized by thick, fleshy polyps that form dome-shaped colonies. They can be differentiated from acans by their skeletal growth and polyp structure, which is typically larger and more inflated. Their colors range from bright reds and oranges to deep greens and contrasting patterns that glow under actinic lighting.

Natural Habitat

Native to the Indo-Pacific, Bowerbanki corals inhabit deeper reef slopes, lagoon edges, and semi-shaded reef zones. They thrive in areas with moderate light and low to moderate water flow, conditions that influence their ideal aquarium placement.

Aquarium Care & Setup

To keep Bowerbanki corals healthy and colorful, aim for stable reef parameters:

• Temperature: 74–80°F (23–27°C)

• pH: 8.1–8.4

• Salinity: 1.024–1.026

• Lighting: Moderate (50–150 PAR)

• Flow: Gentle to moderate; avoid strong, direct currents

• Placement: Lower rockwork or sandbed with plenty of room to expand

Feeding Bowerbanki Corals

While they rely heavily on photosynthesis, Bowerbanki corals respond extremely well to feeding. Target feeding with mysis shrimp, brine shrimp, or coral pellets helps promote faster growth, brighter coloration, and overall health. Feeding 2–3 times weekly is ideal.

Growth and Behavior

Bowerbanki grow moderately, forming encrusting and dome-shaped colonies. They extend fleshy polyps during the day and deploy sweeper tentacles at night for defense. Their steady growth makes them suitable for both smaller mixed reefs and larger coral-dominated systems.

Tankmates

Peaceful reef fish such as clownfish, gobies, wrasses, and tangs are excellent tankmates. Avoid butterflyfish, angelfish, and other coral nippers that may damage their fleshy polyps. Keep them at a safe distance from aggressive corals with long sweeper tentacles to prevent chemical and physical conflict.

Common Challenges

• Overexposure to light: Can lead to bleaching or tissue loss.

• Strong flow: May prevent polyps from expanding fully.

• Pests: Occasionally targeted by flatworms or nudibranchs.

Conclusion

Bowerbanki corals are vibrant, fleshy LPS corals that bring dramatic texture and color to reef aquariums. With moderate lighting, gentle flow, and regular feeding, they grow into impressive colonies that stand out in any reefscape. For aquarists looking to expand their LPS collection beyond the more common Acanthastrea or Micromussa lordhowensis, Bowerbanki is a rewarding choice.
