Braveheart Chalice Coral (Echinophyllia sp.) prefers stable, low-to-moderate light (PAR 75–150) and gentle, indirect flow that keeps detritus from settling without lifting tissue. Start in shaded, lower areas and slowly move to desired light over 2–3 weeks; sudden bright light can bleach. Maintain temperature 24–26°C (75–79°F), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8–9 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 2–10 ppm, phosphate 0.02–0.08 ppm. Test weekly and avoid rapid swings, especially in alkalinity. Feed 1–2 times per week at night with small meaty foods (mysis, reef roids, finely chopped seafood); target feeding promotes coloration and growth. Amino acids can be used sparingly if nutrients are low.Place the chalice low to mid-level on rockwork or a stable frag tile with the face horizontal to prevent shading and allow even growth. Give 5–8 cm (2–3 in) clearance—sweeper tentacles extend at night and can sting neighbors. Keep distance from aggressive species like torches, galaxea, and some favias; it does well near peaceful soft corals and LPS with space. Acclimate with a 30–45 minute drip and light-screening. Signs of stress include tissue recession from edges, gaping mouth, or sudden paling; reduce light/flow, check parameters, and improve stability. If brown jelly appears, frag away affected tissue and iodine dip. Keep nutrients detectable, clean detritus from the base, and avoid handling the flesh.
