Space Invader Chalice Coral

Space Invader Chalice Coral

Chalice LPS

Overview

Space Invader Chalice Coral shows bright neon green eyes on a mottled purple-black chalice surface. Echinophyllia aspera is a stony, encrusting to plating large-polyp 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 feedings at night, which can support growth and maintain coloration. Place on the sandbed or lower rockwork with space around it, as its sweeper tentacles can sting nearby corals.

Care & Placement

Space Invader Chalice Coral (Echinophyllia aspera) prefers low to moderate light (PAR ~75–150) and gentle, varied flow that keeps detritus off the surface without lifting tissue. Place it low to mid in the tank, starting shaded and increasing light slowly over 2–3 weeks to avoid bleaching. Keep 3–6 inches (8–15 cm) from neighbors; this coral has strong night stings and can harm nearby LPS and soft corals. Stable water is key: temperature 75–78°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 1300–1400 ppm, nitrate 2–10 ppm, phosphate 0.03–0.08 ppm. Test weekly, use a refractometer for salinity, and dose calcium/alkalinity/magnesium as consumption rises.Feed 1–2 times weekly after lights out when feeding tentacles extend: small meaty foods (mysis, finely chopped seafood) or fine coral foods. Turn off pumps, target feed lightly, and avoid overfeeding to limit algae. Acclimate by dipping, inspecting for pests, and light acclimating via screen or lower placement. Common issues: edge recession from alkalinity swings or too much light/flow; pale color from low nutrients; slime or brown jelly in low flow with detritus buildup. If stressed, reduce light intensity, correct parameters, gently increase flow, and improve nutrition. Mount on a stable plug or ledge; sandbed is fine if not abrasive and kept clean. Compatible with peaceful tankmates; avoid fast-growing mushrooms and aggressive LPS nearby.

FAQ

Frequently Asked Questions

About the Space Invader Chalice Coral

  • Why is my Space Invader Chalice fading from neon green to dull yellow or brown, and the orange eyes look muted?
    It’s usually spectrum, intensity, and nutrients. Aim for blue-heavy light at modest PAR (75–150). Acclimate slowly if increasing light. Keep nitrate detectable (5–15 ppm) and phosphate 0.03–0.1 ppm; ultra-low nutrients wash out color. Maintain stable alkalinity (7.5–8.5 dKH). Too much white light or abrupt changes cause photoinhibition and fading. Color often rebounds with stability.
  • How can I prevent edge recession or dead spots as it plates out?
    This coral grows from the rim, often creating overhangs that shade its base. Mount it on an angled surface so light and flow reach the growing edge. Provide moderate, cross-flow to keep the rim clean. Leave open space around it to expand evenly. If undersides darken, slightly rotate or raise flow rather than boosting intensity.
  • How aggressive is it at night, and how far should I space neighbors?
    Expect long sweepers after lights out, commonly 2–3 inches. Give at least 3–4 inches of clearance in the growth direction to avoid stings. Run fresh carbon and maintain good export if you keep multiple chalices to reduce chemical stress. Avoid placing fleshy LPS directly downstream; this coral can burn them over time.
  • Can it adapt to higher light if I want faster growth or brighter pop?
    Yes, but do it gradually. Start at ~75–100 PAR and increase 10–15% weekly using screens or shorter photoperiods. Keep nutrients non-zero and raise flow as intensity rises to prevent tissue lifting. Watch for rim paling or retracted eyes—signs you’ve gone too far. Many find best balance around 100–150 PAR under strong blues.
