Cotton Candy Goniopora Coral (Goniopora sp.) prefers stable, nutrient-rich reef conditions with moderate light and gentle, indirect flow that keeps polyps swaying and prevents detritus from settling. Target 80–150 PAR; start low and increase over 1–2 weeks to prevent bleaching. Provide intermittent, broad flow rather than a direct jet. Feed small-particle foods (reef zooplankton, rotifers, enriched brine nauplii, or mixed powdered coral foods) 2–3 times weekly; briefly pause pumps, offer small amounts, and avoid coating tissue. Maintain temp 24–26°C (75–79°F), salinity 1.025–1.026, pH 8.0–8.4, alkalinity 8.0–9.5 dKH, calcium 420–460 ppm, magnesium 1300–1400 ppm, nitrate 2–10 ppm, phosphate 0.03–0.08 ppm. This coral is sensitive to rapid swings, especially alkalinity; test weekly and make small adjustments.Place mid to low in the tank on a stable rock ledge or sandbed “island.” Allow 3–6 inches (7–15 cm) of space for full polyp extension and to avoid contact with stinging neighbors (keep clear of Euphyllia, Galaxea, and aggressive favias). Peaceful tankmates are best; Goniopora rarely attacks others but is easily damaged. Acclimate with a 30–45 minute drip and use light-diffusing screen for the first week. Watch for tissue recession (often from insufficient flow or detritus), poor extension (too much light/flow or low nutrients), and brown jelly infections; frag or siphon and dip promptly if jelly appears. Rinse or baste the colony weekly to lift debris, keep nutrients non-zero, and use quarantine/dips to prevent pests like vermetid snails. Polyps extending fully during the light cycle signal good health.
