Why does my Fruit Ninja Chalice Coral lose fluorescence under higher PAR while other LPS look fine?

Echinophyllia sp. often come from shaded, turbid slopes and channel more pigment to cope with blue-heavy, lower PAR light. High PAR, especially with strong white/red, can wash out fluorescence or cause edge recession. Shift placement to lower light, bias spectrum toward blue/violet, and ramp changes slowly over 2–3 weeks. Slightly elevated nutrients (not ultra-low) help maintain coloration.

The rim is plating upward and shading the eyes—how do I keep growth even without fragging the whole colony?

Rotate the frag/colony 45–90 degrees every few weeks to redistribute light. Provide cross-flow so detritus doesn’t collect under shelves. Trim just the overhanging rim with a diamond band saw, leaving margins between eyes. After trimming, reduce light 20–30% for a week and use an iodine dip to speed recovery.

I’m seeing slow tissue recession from one edge—what’s the best emergency protocol for chalices?

First, check stability: alkalinity swings are a common trigger. Increase random flow slightly to deter biofilm, but avoid direct blasts. Perform an iodine bath, then micro-frag 3–5 mm ahead of the recession line between eyes, discarding compromised tissue. Mount frags on clean plugs, lower PAR temporarily, and run fresh carbon to reduce chemical stress from neighboring soft corals.

Are there pests specific to Echinophyllia I should watch for beyond the usual suspects?

While true species-specific predators are rare, look for small planaria-like flatworms, vermetid snail irritation, and filamentous algae invading fresh cuts. Inspect at night for opaque nudi-like grazers near eyes. A turkey baster blast test helps reveal clingy pests. Quarantine with periodic dips (iodine, followed by a gentle rinse) and manually remove vermetids to prevent chronic polyp retraction.

TSA Fruit Ninja Chalice Coral

Chalice LPS

Overview

Fruit Ninja Chalice Coral shows a flattened, ridged plate with bright contrasting eyes. Echinophyllia sp. is a hard plating LPS coral that prefers low to moderate light and gentle to moderate water flow. It relies on symbiotic algae for energy but benefits from occasional small meaty foods at night, which can speed growth and deepen coloration. Place on the sandbed or isolated rock with space around it, as long sweeper tentacles can sting nearby corals.

Care & Placement

Fruit Ninja Chalice Coral (Echinophyllia sp.) prefers stable, mature systems with consistent nutrients and gentle conditions. Provide moderate to low light (PAR ~75–150); start shaded and increase slowly over 2–3 weeks to avoid bleaching. Use low to moderate, indirect flow—enough to keep detritus off the surface without lifting tissue. Target feed small meaty foods or zooplankton 1–2 times weekly after lights out when feeding tentacles extend; this supports growth and color. Keep 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 2–15 ppm, and phosphate 0.03–0.08 ppm. Test weekly and dose to hold steady numbers; swings often cause tissue recession. Use a PAR meter if possible and run carbon to reduce chemical warfare from soft corals.Place low to mid in the tank on a flat rock with enough space for plating growth. Keep 3–6 inches from neighbors; Echinophyllia can extend stinging sweepers at night. Avoid direct sand contact to prevent abrasion. Drip acclimate for 30–45 minutes, dip for pests, and light-acclimate with a screen or reduced intensity. Handle by the skeleton, not the flesh. Watch for pale tissue (too much light), browned-out color (too little light or excess nutrients), and receding edges (alkalinity swings, pests, or low flow). Increase flow slightly to keep the surface clean, adjust light gradually, and improve feeding if growth stalls. Quarantine new corals when possible.
