Why does my Freaky Friday Chalice develop sharp ridges and plate outward instead of staying flat?

Echinophyllia aspera often starts encrusting, then forms undulating plates as it seeks stable light and flow. Strong directional flow can sculpt ridges; moderate, diffuse flow keeps plates smoother. If the rim stalls or burns, check for light creep during acclimation and alkalinity swings. Mount at a slight angle to shed detritus; sitting flat traps debris and bacteria, slowing edge growth.

My chalice’s reds have dulled to rust while greens look muted—what drives these shifts?

Spectrum and nutrients play big roles. Heavy white or very low nutrients wash out reds; slightly elevated nitrate (2–10 ppm) with strong blue/violet restores saturation. Keep potassium near NSW (~380–420 ppm) for reds and oranges. Avoid sudden PAR jumps; gradual increases preserve fluorescence. Carbon use helps when soft corals release allelopathic compounds that mute color.

The rim is receding at night, but daytime polyp extension looks fine—what’s going on?

Nocturnal sweeper activity and micro-irritants are likely. E. aspera deploys long sweepers after lights out; nearby stony corals or vermetid mucus can trigger localized recession. Increase spacing (8–10 cm or more), trim vermetids, and add a bit more random flow across the rim to prevent film buildup. Stabilize alkalinity; nighttime pH dips plus alk swings often start edge peel.

What’s the safest way to frag a Freaky Friday Chalice without losing the “eyes”?

Use a diamond saw to cut between mouths, not through them. Make clean, decisive passes; avoid crushing. Dip frags in iodine-based antiseptic, then heal in low light, gentle flow for 1–2 weeks. Glue to a smooth plug so tissue can seal the edge. Feed lightly at night to speed recovery, but keep nutrients stable to prevent bacterial film on the cut line.

TSA Freaky Friday Chalice Coral

Chalice LPS

Overview

Freaky Friday Chalice Coral displays a flattened, undulating plate with raised corallite “eyes” and contrasting coloration. Echinophyllia aspera is a stony, plating coral that prefers low to moderate light and gentle, indirect water flow. It relies on symbiotic algae for energy but benefits from occasional small meaty foods, which can improve growth and maintain color. Place it on a stable surface with room to expand, and keep distance from neighbors due to nighttime sweeper tentacles that can sting.

Care & Placement

Freaky Friday Chalice Coral (Echinophyllia aspera) prefers stable, clean water and gentle conditions. Place it low to mid in the tank, shaded from intense light; aim for 50–150 PAR to prevent bleaching and washed-out color. Provide low to moderate, indirect flow so the surface stays clean without tissue lift; detritus on the rim can cause recession. Target feed 2–3 times weekly after lights out with small meaty foods (mysis, roe, finely minced seafood) or a fine coral blend; you’ll see feeding tentacles extend at night. Keep temperature 75–79°F (24–26°C), pH 8.1–8.4, salinity 1.025–1.026, calcium 400–450 ppm, alkalinity 8.0–9.5 dKH, magnesium 1300–1400 ppm, nitrate 2–10 ppm, and phosphate 0.03–0.08 ppm. Test weekly and avoid rapid swings, especially in alkalinity and temperature.Mount on a flat rock with room to grow outward; leave 3–6 inches from neighbors. This coral can sting via sweepers and mesenterial filaments, so treat it as semi‑aggressive. Acclimate with a slow drip and light acclimation (reduced photoperiod or screen layers over a week). Rinse or dip new pieces to limit pests. Watch for paling (too much light or too little nutrients), edge recession (flow or detritus issues), and brown jelly; siphon, iodine dip, and frag away dead tissue if needed. Keep sand off the flesh, use a PAR meter if possible, and maintain steady nutrients for color and growth.
