Why does my Bright Side of the Moon Chalice lose fluorescence under stronger lights?

Echinophyllia sp. often shifts pigments with PAR and spectrum. High PAR and excess white light can wash colors and thin tissue at the rim. Move it lower, reduce whites, and favor a blue-heavy spectrum. Increase light slowly (10–15% weekly). Keep NO3 around 5–15 ppm and PO4 0.03–0.1 to prevent paling from ultra-low nutrients.

The rim is receding while the center looks fine—what’s the likely cause?

Edge recession usually points to light or flow stress at the growing margin, sometimes compounded by alkalinity swings. Check PAR at the rim; strong laminar flow can peel tissue. Stabilize dKH (8–9), reduce direct flow, and perform an iodine dip if tissue looks compromised. Offer small target feeds during recovery to fuel regrowth.

How far can its sweepers reach at night, and how do I prevent chemical warfare?

Bright Side of the Moon Chalice can extend 2–3 inch sweepers after lights out, stinging nearby corals. Give at least 3–4 inches of clearance on all sides, more if neighbors are aggressive. Run carbon and ensure intermittent, not blasting, flow to dilute allelopathic compounds. Nighttime observation helps you fine-tune spacing.

It stopped putting out feeding tentacles—should I still target feed?

Withheld tentacles often indicate stress from changes in light, flow, or parameters. Don’t force heavy feeding; excess foods can fuel film bacteria that irritate tissue. Instead, correct stability first, then try tiny portions of fine meaty foods at the same time each evening. Gentle, predictable cues help reestablish feeding response.

Chalice LPS

Overview

Bright Side of the Moon Chalice Coral shows a low, undulating plate with bright eyes and a scalloped rim. Echinophyllia sp. is a stony, plating large-polyp species that prefers low to moderate light and gentle to moderate flow. It is photosynthetic via symbiotic algae but benefits from occasional small meaty foods at night, which can support faster growth and richer color. Place on the sandbed or lower rockwork with space around it, as sweeper tentacles can sting nearby corals.

Care & Placement

Bright Side of the Moon Chalice Coral (Echinophyllia sp.) prefers stable, low-to-moderate light and gentle, indirect flow. Target 75–150 PAR; acclimate from lower light using shade or screen over 1–2 weeks to avoid bleaching. Provide low, laminar-to-random flow that keeps detritus off the surface without lifting tissue; aim powerheads past, not at, the coral. Feed 2–3 times weekly at night with small meaty foods (mysis, brine, reef roids) or amino/FA supplements to support color and growth. Maintain: temperature 24–26°C (75–79°F), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8.0–9.5 dKH (avoid swings), calcium 400–450 ppm, magnesium 1300–1400 ppm, nitrate 2–15 ppm, phosphate 0.03–0.08 ppm. Use reliable test kits, an ATO for salinity stability, and a PAR meter or light map for consistency.Place low to mid in the tank on a stable rock ledge; avoid sand contact to prevent abrasion. Space 4–6 inches from neighbors—Echinophyllia has strong nighttime sweeper tentacles and can overgrow slower corals. Peaceful tank mates are fine; keep away from aggressive LPS and fast encrusters. Drip acclimate 30–45 minutes and dip to check for pests. Common issues: bleaching (too much light—lower PAR, increase feeding), tissue recession (alk swings or detritus—stabilize chemistry, adjust flow, siphon debris), bacterial spots (improve flow, consider an iodine dip). For fragging, use a wet saw and allow healed edges before moving. Regular, modest feeding and rock-solid stability are the keys to success.
