How do I keep Galaxy Quest Chalice Coral’s colors from fading or browning under LEDs?

Aim for moderate PAR (75–150) with strong blue/violet (420–460 nm). Acclimate slowly from shade; sudden bright light washes reds and can mute yellows. Maintain stable alk (8–9.5 dKH) and moderate nutrients (NO3 5–15 ppm, PO4 0.03–0.1 ppm). Overly low nutrients pale it; high nutrients dull it. Periodic, small target feedings help saturation without fueling algae.

My colony’s rim is receding while the center looks fine—what’s the likely cause and fix?

Edge recession often follows light shock, alkalinity swings, or chronic irritation (vermetid snails, detritus traps). First, stabilize parameters and reduce light 20–30% for a week. Remove vermetids and improve flow to the rim. Do a short iodine dip. If recession advances, cut a safety margin into healthy tissue with a saw and seal the cut edge with gel glue.

What and when should I feed for faster growth without fouling the tank?

Feed after lights dim when feeder tentacles appear. Offer small particle foods (reef plankton, roe) with occasional finely minced mysis; avoid large chunks sitting on tissue. Target feed 1–2× weekly. Turn off flow briefly, then resume gentle flow to clear leftovers. Overfeeding can fuel film algae that irritates the rim and slows calcification.

How aggressive is it, and how should I place it relative to neighbors?

At night it can deploy mesenterial filaments that digest nearby tissue. Give 3–4 inches clearance down-current from more delicate LPS and encrusters. Keep it off rough sand that can abrade the rim. Run fresh carbon and maintain good export if mixing with chemically expressive corals. Watch for stings on acans, favias, and small encrusters.

Chalice LPS

Overview

Galaxy Quest Chalice Coral displays a thin, plating form with raised ridges and distinct round mouths. Echinophyllia sp. is a large-polyp stony coral that grows as an encrusting to plating sheet; it prefers low to moderate light and gentle, indirect water flow. It hosts symbiotic algae for most nutrition but accepts occasional small meaty feedings, which can speed growth and deepen color. Place it on a stable surface with space around it, as nighttime sweeper tentacles can sting nearby corals.

Care & Placement

Galaxy Quest Chalice Coral (Echinophyllia sp.) thrives under low to moderate light (PAR 50–150). Start shaded and increase exposure slowly over 2–3 weeks to avoid bleaching; use mesh screens or reduced photoperiod for light acclimation. Provide gentle, indirect flow that keeps the surface free of detritus without lifting flesh; too much flow causes tissue pullback. Place on the sandbed or lower rockwork on a stable, flat area to allow plating growth. Keep 3–6 inches from neighbors; it can extend short sweeper tentacles at night and will sting soft corals and other LPS. Ideal parameters: temperature 75–79°F (24–26°C), salinity 1.025–1.026 (35 ppt), pH 8.0–8.4, alkalinity 8.0–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 2–10 ppm, phosphate 0.03–0.08 ppm. This coral dislikes rapid swings, especially in alkalinity and temperature; test weekly and use a PAR meter if possible. Feed 1–2 times per week after lights out with small meaty foods (mysis, roe, finely chopped seafood) or a coral food slurry; target feed lightly to avoid fouling. Quarantine and dip before adding, then drip acclimate 30–45 minutes. Watch for pale tissue (too much light), receding edges (low nutrients or unstable alkalinity), or brown film (poor flow); adjust placement, stabilize parameters, and gently baste detritus. Run fresh carbon and give extra space when mixing with aggressive LPS.
