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

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

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

The Red Bullseye Rock Mushroom (Rhodactis<\/em> sp.) is a striking and resilient soft coral (Corallimorpharian)<\/strong> renowned for its brilliant red colouration<\/strong> and bullseye-like concentric patterning<\/strong>. Its large, fleshy oral disc displays rich tones of red, crimson, and maroon<\/strong>, often highlighted with hints of orange, pink, or metallic green under blue-spectrum lighting. The surface is covered with short, textured vesicles, giving the coral a soft, velvety look and enhancing its light reflection. Hardy, adaptable, and low maintenance, this coral is a superb choice for aquarists seeking to add a bold splash of colour to shaded or low-light areas of a reef aquarium.<\/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>. Found on protected reef slopes, lagoonal areas, and under rock ledges<\/strong>, where lighting is moderate to low and water movement is gentle.<\/p>\n

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

The Red Bullseye Mushroom Coral is photosynthetic<\/strong>, hosting zooxanthellae<\/strong> that provide most of its energy. Supplemental feeding supports growth and enhances pigmentation. Feed 1\u20132 times per week<\/strong> with:<\/p>\n

    \n
  • \n

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

  • \n

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

  • \n

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

    Target feeding with a pipette or baster is beneficial, especially in lower-light areas or during recovery.<\/p>\n

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

    Low to moderate lighting.<\/strong> Rhodactis<\/em> corals prefer diffused or subdued light and may bleach or shrink under overly intense illumination.<\/p>\n

      \n
    • \n

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

    • \n

      Ideal for shaded rockwork, under overhangs, or lower aquarium zones.<\/p>\n<\/li>\n

    • \n

      Blue and actinic spectrums enhance the coral\u2019s deep red fluorescence and contrast beautifully against surrounding corals.<\/p>\n<\/li>\n<\/ul>\n

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

      Low to moderate, indirect flow.<\/strong> Gentle, varied water movement encourages full expansion and helps prevent debris buildup. Avoid direct, strong currents that may cause retraction or tissue damage.<\/p>\n

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

        Place on lower rockwork or substrate<\/strong>, in areas with gentle flow and indirect light.<\/p>\n<\/li>\n

      • \n

        Ensure ample space<\/strong> around the coral \u2014 Rhodactis<\/em> can grow large and may expand to several inches across.<\/p>\n<\/li>\n

      • \n

        Avoid proximity to aggressive LPS corals or stinging species.<\/p>\n<\/li>\n

      • \n

        Excellent for shaded aquascape zones or low-light corners of mixed reef systems.<\/p>\n<\/li>\n<\/ul>\n

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

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

          \n
        • \n

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

        • \n

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

        • \n

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

          Avoid:<\/p>\n

            \n
          • \n

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

          • \n

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

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

            Moderate.<\/strong> While Rhodactis<\/em> does not have long sweeper tentacles, it can release mild toxins (allelopathy) and overgrow neighbouring corals. Maintain sufficient spacing to prevent competition or contact.<\/p>\n

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

            Beginner.<\/strong> The Red Bullseye Mushroom Coral is hardy, adaptable, and forgiving \u2014 suitable for aquarists of all skill levels. It thrives in a wide range of water conditions and makes an excellent choice for both nano and large reef aquariums.<\/p>\n

              Stable water chemistry and moderate nutrients will help maintain the coral\u2019s intense red hues and promote steady growth.<\/p>\n

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

              Fully reef safe.<\/strong> The Red Bullseye Rock Mushroom Coral is a vibrant, low-maintenance coral that thrives in shaded environments where many other species struggle. Its bright colouration and unique texture make it a standout feature in any soft or mixed reef aquarium.<\/p>\n

              \n

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

              Rhodactis<\/em> mushrooms can inflate or fold their oral discs<\/strong> to manipulate water flow and light exposure \u2014 a behaviour that also helps them capture drifting food particles from the surrounding water.<\/p>\n","protected":false},"excerpt":{"rendered":"
