Green Bubble Hard Coral (Plerogyra sp.)<\/strong><\/h2>\n

(Also known as Green Bubble Coral, Pearl Coral, or Grape Coral)<\/em><\/p>\n

Overview<\/strong><\/h3>\n

The Green Bubble Coral (Plerogyra<\/em> sp.) is a captivating large-polyp stony (LPS) coral<\/strong> recognised for its large, inflated bubble-like vesicles<\/strong> that shimmer with a distinctive green or metallic hue under aquarium lighting. Each bubble expands during the day to absorb light and contracts at night to reveal long, feeding tentacles. This coral\u2019s unique texture, colour, and motion make it a standout centrepiece in any reef aquarium. While hardy and forgiving, Plerogyra<\/em> requires low flow, moderate light, and ample space<\/strong> due to its delicate tissue and long sweeper tentacles.<\/p>\n

Origin<\/strong><\/h3>\n

Native to the Indo-Pacific region<\/strong>, including the Coral Sea, Fiji, Tonga, Indonesia, and the Great Barrier Reef. Found in sheltered reef slopes and lagoon environments<\/strong>, often attached to rubble or within crevices where flow and light are moderate.<\/p>\n

Feeding<\/strong><\/h3>\n

The Green Bubble Coral is photosynthetic<\/strong>, containing zooxanthellae<\/strong> that supply most of its nutritional needs. Supplemental feeding encourages growth, tissue expansion, and vibrant colour. Offer 1\u20132 feedings per week<\/strong> of:<\/p>\n

    \n
  • \n

    Mysis shrimp, brine shrimp, or finely chopped seafood<\/p>\n<\/li>\n

  • \n

    Marine snow or coral plankton blends<\/p>\n<\/li>\n

  • \n

    LPS-specific coral foods<\/p>\n<\/li>\n<\/ul>\n

    Feed when tentacles are visible (usually after lights dim). Gently target feed near extended polyps for best results.<\/p>\n

    Lighting<\/strong><\/h3>\n

    Low to moderate lighting.<\/strong> Plerogyra<\/em> prefers subdued, indirect illumination to prevent bleaching or overexposure.<\/p>\n

      \n
    • \n

      PAR range: 75\u2013150 \u00b5mol\/m\u00b2\/s<\/strong><\/p>\n<\/li>\n

    • \n

      Avoid direct, intense light; shaded or lower-tank areas are ideal.<\/p>\n<\/li>\n

    • \n

      Blue and actinic lighting enhances its fluorescent green glow.<\/p>\n<\/li>\n<\/ul>\n

      Water Flow<\/strong><\/h3>\n

      Low to moderate, indirect flow.<\/strong> Gentle, consistent movement helps remove debris without damaging the inflated vesicles. Strong flow can tear the coral\u2019s delicate tissue or cause it to retract for prolonged periods.<\/p>\n

      Placement<\/strong><\/h3>\n
        \n
      • \n

        Place on sandy substrate<\/strong> or in low-flow, shaded areas of the lower rockwork<\/strong>.<\/p>\n<\/li>\n

      • \n

        Ensure plenty of space (15\u201320 cm \/ 6\u20138 inches)<\/strong> around the coral \u2014 it extends long, stinging sweeper tentacles at night.<\/p>\n<\/li>\n

      • \n

        Avoid sharp rock edges that could puncture its soft bubbles.<\/p>\n<\/li>\n<\/ul>\n

        Tank Mates<\/strong><\/h3>\n

        Reef safe with caution.<\/strong> Compatible with:<\/p>\n

          \n
        • \n

          Peaceful reef fish (clownfish, gobies, tangs, blennies, etc.)<\/p>\n<\/li>\n

        • \n

          Reef-safe invertebrates such as snails, hermits, and shrimp<\/p>\n<\/li>\n

        • \n

          Other LPS and soft corals placed at a safe distance<\/p>\n<\/li>\n<\/ul>\n

          Avoid:<\/p>\n

            \n
          • \n

            Aggressive or stinging corals (e.g., Euphyllia, Galaxea, Hydnophora)<\/p>\n<\/li>\n

          • \n

            Butterflyfish, large angelfish, or puffers that may nip at its tissue<\/p>\n<\/li>\n<\/ul>\n

            Aggression<\/strong><\/h3>\n

            Moderately aggressive.<\/strong> At night, Plerogyra<\/em> extends long, powerful sweeper tentacles<\/strong> capable of stinging and damaging nearby corals. Provide ample spacing to prevent chemical or physical conflict.<\/p>\n

            Experience Level<\/strong><\/h3>\n

            Beginner to intermediate.<\/strong> Hardy and adaptable when placed correctly, the Green Bubble Coral is suitable for aquarists with basic LPS experience. It thrives in stable reef environments with consistent lighting, gentle flow, and good water quality.<\/p>\n

              Reef Compatibility<\/strong><\/h3>\n

              Reef safe with caution.<\/strong> The Green Bubble Coral is a beautiful, peaceful showpiece that adds volume, texture, and colour to LPS or mixed reefs. With careful placement and moderate lighting, it can thrive for years, inflating fully each day to display its radiant green shimmer.<\/p>\n","protected":false},"excerpt":{"rendered":"
