Bullseye Rock Mushroom (Fungiidae Coral) (Coloured Rhodactis sp.)<\/strong><\/h2>\n

(Also known as Bullseye Mushroom Coral, Hairy Mushroom Coral, or Elephant Ear Mushroom Coral)<\/em><\/p>\n

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

The Bullseye Rock Mushroom (Rhodactis<\/em> sp.) is a stunning and hardy soft coral (Corallimorpharian)<\/strong> known for its distinctive bullseye patterning<\/strong>, textured surface<\/strong>, and vibrant coloration<\/strong>. Its large, fleshy oral disc displays concentric rings of colour \u2014 often in green, blue, red, orange, and purple<\/strong> \u2014 creating a striking \u201ctarget\u201d appearance. Covered in short, tentacle-like vesicles, Rhodactis<\/em> mushrooms have a more textured look than Discosoma<\/em> species, giving them a soft, velvety character under aquarium lighting. Highly adaptable and easy to maintain, this coral is ideal for aquarists looking to add both colour and dimension to shaded areas of the reef.<\/p>\n

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

Native to the Indo-Pacific region<\/strong>, including the Great Barrier Reef, Coral Sea, Fiji, Tonga, Indonesia, and the Solomon Islands<\/strong>. Typically found on reef slopes, lagoon substrates, and shaded rocky outcrops<\/strong>, where light and flow are moderate to low.<\/p>\n

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

The Bullseye Mushroom Coral is primarily photosynthetic<\/strong>, deriving most of its nutrition from zooxanthellae<\/strong> within its tissue. However, it readily accepts supplemental feeding, which enhances colour vibrancy and growth. Feed 1\u20132 times per week<\/strong> with:<\/p>\n

    \n
  • \n

    Finely chopped seafood (shrimp, clam, fish)<\/p>\n<\/li>\n

  • \n

    Mysis or enriched brine shrimp<\/p>\n<\/li>\n

  • \n

    Marine snow or coral food powders<\/p>\n<\/li>\n<\/ul>\n

    Target feeding encourages faster growth and helps maintain bold colouration.<\/p>\n

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

    Low to moderate lighting.<\/strong> Rhodactis<\/em> corals prefer soft, diffused light and can bleach if exposed to excessive intensity.<\/p>\n

      \n
    • \n

      PAR range: 50\u2013150 \u00b5mol\/m\u00b2\/s<\/strong><\/p>\n<\/li>\n

    • \n

      Ideal placement in shaded areas or lower rockwork.<\/p>\n<\/li>\n

    • \n

      Blue-spectrum or actinic lighting brings out fluorescent green and red tones.<\/p>\n<\/li>\n<\/ul>\n

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

      Low to moderate, indirect flow.<\/strong> Gentle movement allows the coral to open fully and prevents debris accumulation. Strong or direct currents can cause retraction or detachment.<\/p>\n

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

        Place on lower rockwork<\/strong> or substrate<\/strong>, away from aggressive stinging corals.<\/p>\n<\/li>\n

      • \n

        Ensure space for expansion \u2014 Rhodactis<\/em> can grow large and spread over time.<\/p>\n<\/li>\n

      • \n

        They attach easily to rock and can propagate by tissue division, forming attractive clusters or carpets.<\/p>\n<\/li>\n

      • \n

        Avoid sharp rocks that may damage their fleshy surface.<\/p>\n<\/li>\n<\/ul>\n

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

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

          \n
        • \n

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

        • \n

          Invertebrates such as shrimp, snails, and hermit crabs<\/p>\n<\/li>\n

        • \n

          Other soft corals, zoanthids, and non-aggressive LPS species<\/p>\n<\/li>\n<\/ul>\n

          Avoid:<\/p>\n

            \n
          • \n

            Aggressive corals with long sweeper tentacles (e.g., Euphyllia, Galaxea, Hydnophora)<\/p>\n<\/li>\n

          • \n

            Butterflyfish or large angelfish that may pick at soft tissue<\/p>\n<\/li>\n<\/ul>\n

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

            Moderate.<\/strong> Rhodactis<\/em> can release mild toxins and overgrow slower-growing neighbours. It is best to provide spacing to prevent contact with other coral species.<\/p>\n

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

            Beginner.<\/strong> The Bullseye Rock Mushroom Coral is exceptionally hardy, making it suitable for reef keepers of all experience levels. It tolerates a wide range of conditions and adds vibrant colour and movement with minimal maintenance.<\/p>\n

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

              Fully reef safe.<\/strong> The Bullseye Rock Mushroom Coral is a visually captivating, low-maintenance coral that thrives in shaded, low-flow environments. Its bullseye pattern and rich colours make it a standout addition to mixed or soft coral reef aquariums.<\/p>\n

              Interesting Fact<\/strong><\/h3>\n

              Rhodactis<\/em> mushrooms can inflate their oral discs<\/strong> dramatically to aid in feeding or to move across rockwork. In some cases, they have been observed capturing small fish or shrimp \u2014 a reminder of their anemone-like feeding abilities.<\/p>\n","protected":false},"excerpt":{"rendered":"
