Description
Anacropora – Anacropora spp.
Anacropora spp., known simply as the Anacropora, is a distinctive and underrated small-polyp stony (SPS) coral admired for its intricate, bush-like structure and fine, delicate branches. Often referred to as the “bottlebrush coral,” it forms dense, interwoven colonies that provide both visual complexity and movement to the reef. Unlike Acropora, its branches are thinner and more flexible, giving it a softer aesthetic while maintaining vibrant coloration—ranging from electric green and sky blue to pastel pink and lavender. When placed under blue-dominant lighting, Anacropora exhibits striking fluorescence, with its polyps creating a shimmering, velvety texture across the colony.
Lighting: Moderate to high (180–300 PAR); strong blue and UV spectrum lighting enhances fluorescence and branch definition
Flow: Moderate to strong; thrives in multidirectional, turbulent current that prevents debris buildup and ensures robust skeletal development
Placement: Middle to upper regions of the aquarium; provide ample space for branching expansion and avoid direct contact with aggressive corals
Temperature: 76–80°F (24–27°C)
Salinity: 1.025–1.026 SG
pH: 8.1–8.4
Alkalinity: 8–9 dKH; maintain strict stability to prevent branch tip necrosis
Calcium: 420–460 ppm
Magnesium: 1300–1400 ppm
Nutrients: Low to moderate (NO₃ 2–10 ppm, PO₄ 0.02–0.08 ppm); slightly elevated nutrients improve tissue vibrancy and polyp extension
Feeding: Primarily photosynthetic; benefits from weekly broadcast feeding with amino acids or fine coral plankton to enhance coloration and branch density
Aggression: Low; non-stinging but may grow into nearby corals if space is limited
Growth Rate: Fast; forms dense, upward-branching colonies under consistent lighting and strong flow
Care Level: Intermediate – resilient under stable SPS conditions but sensitive to rapid changes in alkalinity or light intensity
Compatibility: Peaceful; excellent for SPS-dominated reefs, pairing beautifully with Acropora, Seriatopora, and Montipora species to create natural, multi-textured structure
