Why does my Golden Eye Chalice lose its gold “eyes” under brighter lights?

Echinophyllia often comes from deeper, blue-rich zones. Excess PAR or white-heavy spectrum can wash out pigments and shrink oral discs. Aim for 75–150 PAR, blue-biased lighting, and stable nutrients (not ultra-low). Gradually acclimate downward if bleaching starts. Small increases in iron can deepen greens; keep potassium 380–420 ppm to support color without pushing browning.

The rim is receding while the center looks fine—how can I stop the tissue loss?

Edge recession usually follows alkalinity or salinity swings, detritus buildup at the margin, or vermetid irritation. Siphon debris, increase gentle crossflow at the rim, and stabilize dKH 8–9 with minimal daily swing. You can seal the dying edge with a thin ring of gel superglue to halt spread, then do an iodine dip and run fresh carbon.

My chalice inflates at night but stays flat by day—is that normal or stress?

Nighttime swelling with feeder tentacles extended is a feeding posture. If it stays deflated by day yet color holds, that’s typical. Concern arises if you see persistent daytime deflation with paling or exposed skeleton—check for alkalinity instability, rapid nutrient drops, or excessive PAR. Try evening target feeding of fine meaty foods to improve vigor.

Are there hidden aggression risks when placing this chalice near other LPS?

Yes. Echinophyllia can deploy short sweepers and potent mesenterial filaments after lights out. Give 3–4 inches clearance, more near Galaxea, Favia, or torch corals. Avoid direct line-of-fire from vermetid snails and don’t place where detritus settles. Running carbon and maintaining good flow reduce chemical stress from neighboring soft corals.

TSA Golden Eye Chalice Coral

Chalice

Overview

Golden Eye Chalice Coral shows a flattened, undulating plate with bright yellow to gold eyes across a darker base. Echinophyllia sp. is a stony, plating LPS coral that prefers low to moderate light and gentle to moderate water flow. It is photosynthetic via symbiotic algae but accepts small meaty foods at night; occasional target feeding can support growth and color. Place on stable rock with space around it, as sweeper tentacles can sting nearby corals.

Care & Placement

Golden Eye Chalice Coral (Echinophyllia sp.) thrives under stable, nutrient-balanced conditions with low to moderate light and gentle, indirect flow. Aim for 75–150 PAR; start on the lower side and increase slowly to avoid bleaching and receding edges. Provide low–moderate, crossflow movement to keep detritus from settling while preventing tissue irritation. Target feed 2–3 times weekly after lights out with small meaty foods (mysis, reef roids, finely chopped seafood); briefly pause pumps during feeding. Maintain: temperature 24–26°C (75–79°F), salinity 1.025–1.026, pH 8.0–8.4, alkalinity 8.0–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1400 ppm, nitrate 5–15 ppm, phosphate 0.03–0.08 ppm. Use reliable test kits and prioritize stability; this coral is sensitive to abrupt parameter swings and overly intense light. Place low to mid in the tank on a stable rock or protected sandbed, leaving 3–6 inches from neighbors; expect strong nighttime sweeper activity and potential mesenterial filaments, so avoid contact with other corals. Acclimate by dipping for pests, drip acclimating 30–45 minutes, and shading 1–2 weeks. Common issues: pale color (too little nutrient/light), tissue recession (alk swings, direct flow), and sediment abrasion on the rim—adjust placement, flow, and nutrients accordingly. Keep an auto top-off for salinity stability and inspect regularly for recession so you can frag away dying edges if needed.
