Why does my Pink Branching Cyphastrea lose pink coloration or turn beige under new lights?

This species prefers moderate to low PAR. Sudden exposure to high intensity often washes out pinks, starting at branch tips. Acclimate over 2–3 weeks with reduced photoperiod or screen layers. In very low light it may brown or beige. Aim for 80–150 PAR, stable alkalinity (8–9 dKH), and moderate nutrients to maintain saturation without paling.

How can I encourage branching rather than just encrusting growth?

Mount a small branch horizontally on a plug so multiple axial tips can form upward shoots. Provide steady, indirect flow to keep tissue clean. Keep neighboring surfaces clear so the base can encrust for stability; once a “foot” forms, growth often shifts vertical. Regular micro-feeding at night supports tip formation, especially after fragging stress.

My colony retracts at night and shows tiny feeder tentacles—should I target feed?

Yes. Cyphastrea has small polyps that feed after lights out. Offer fine foods (rotifers, reef chili/roids, or enriched nauplii) 1–2 times weekly with pumps on low for 10–15 minutes. Overfeeding can foul tissue in low flow, so baste the colony gently afterward. Expect improved tissue thickness and color depth over several weeks.

The base is receding while branch tips look fine—what’s the likely cause?

Basal recession often points to instability rather than pests: alk swings, detritus buildup under the base, or Vermetid irritation. Check alkalinity drift, increase gentle cross-flow to keep the base clean, and remove nearby Vermetids. Inspect for shadowing that starves the base; slight repositioning to diffuse light can halt recession and allow re-encrustment.

Pink Branching Cyphastrea Coral

Cyphastrea

Overview

Pink Branching Cyphastrea Coral shows tight, knobby branches with small polyps covering each surface. Cyphastrea decadia is a branching stony coral that prefers low to moderate light and gentle to moderate, indirect water flow. It is photosynthetic via symbiotic algae but will accept small particulate foods; occasional feeding can support growth and coloration. Place on stable rockwork with some space from stinging corals, and acclimate slowly if moving to brighter areas.

Care & Placement

Pink Branching Cyphastrea Coral (Cyphastrea decadia) thrives with low to moderate light and moderate, random flow. Target 50–120 PAR; start low and increase slowly to prevent bleaching. Provide indirect, cross-current flow to keep polyps clean and reduce detritus buildup without blasting the tissue. Place low to mid in the tank, on stable rock with room to grow; this coral is generally peaceful but can encrust and overtake nearby surfaces, so leave 2–3 inches from neighbors and avoid placing near aggressive LPS with long sweeper tentacles. Feed fine particulate foods (reef plankton, rotifers, powdered coral foods) 1–3 times weekly, preferably after lights out when polyps extend; broadcast feeding is usually sufficient.Maintain stable water: temperature 75–78°F (24–26°C), salinity 1.025–1.026 SG, pH 8.1–8.4, alkalinity 8.0–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 2–15 ppm, phosphate 0.03–0.10 ppm. Use reliable test kits and keep salinity steady with an auto top-off. Acclimate by dipping for pests, then light acclimate: begin on the sandbed or shaded area and move up over 1–2 weeks. Secure with gel glue or epoxy to prevent falls. Watch for pale tissue (too much light or too little nutrients), browning (excess nutrients or too little light), and recession after alkalinity swings—stability is key. If polyps stay retracted, reduce flow intensity, check for pests, and verify parameters before adjusting placement.
