Potion of Life Blastomussa Coral (Blastomussa wellsi) prefers low to moderate light (50–120 PAR) and gentle, indirect flow that wiggles the tentacles without folding the flesh. Place low to mid in the tank—sandbed or lower rock ledges with partial shade—on a smooth surface so inflated tissue isn’t cut. Keep 2–3 inches from neighbors; it’s generally peaceful with short sweepers, but give space from stingers like Galaxea, Favia, and some Euphyllia. Feed 2–3 times weekly with small meaty foods (mysis, chopped krill, calanus) or fine coral foods; target feed at night or when tentacles extend to support growth and richer color. Maintain stable water: temperature 75–79°F (24–26°C), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8.0–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 5–15 ppm, phosphate 0.03–0.08 ppm. Test weekly with reliable kits, watch alkalinity for swings, and keep nutrients detectable; ultra-low nutrients can pale tissue.Acclimate by dripping 30–45 minutes, then light-acclimate over 1–2 weeks (dimmed lights or a shade screen). Dip and inspect for pests, and quarantine if possible. Avoid strong direct flow, which can cause tissue recession and expose skeleton; use enough movement to prevent detritus collecting between polyps. If bleaching occurs, reduce light and increase shade; if recession starts, check for alkalinity swings, salinity shifts, and hidden pests, then lower flow and improve feeding. Closed polyps often signal irritation or parameter drift—recheck temperature, salinity, and recent changes. Stability and gentle conditions are key for long-term polyp expansion and steady growth.
