Low to moderate light preferred.
PAR range: 50–120.
High light can bleach or dull colors — acclimate slowly if increasing.
Under blue-spectrum lighting, their colors pop most vividly.
Low to moderate, indirect flow.
Too much flow can cause polyps to retract or tissue to tear.
Gentle, random flow keeps detritus off without stressing the coral.
Temp: 76–80°F (24.5–26.5°C)
Salinity: 1.025
pH: 8.1–8.4
Alkalinity: 8–10 dKH
Calcium: 400–450 ppm
Magnesium: 1250–1350 ppm
Nitrates: 1–10 ppm
Phosphates: 0.01–0.05 ppm
Stability is more important than chasing numbers — avoid rapid parameter swings.
Very receptive to feeding, and feeding enhances growth and coloration.
Target feed 2–3x per week (especially at night or when tentacles are visible).
They can puff up dramatically when eating — a fun coral to watch during feeding!
Bottom to mid-level of tank.
Flat rock surfaces or sand bed are ideal.
Ensure polyps don’t get shaded or blasted with flow.
Mild to moderate.
Doesn’t usually send out long sweepers, but may sting nearby tissue if crowded.
Keep 2–3 inches between acans and other LPS corals.
Easy to frag with a bone cutter, dremel, or band saw.
Cut between polyps, not through them.
Heals relatively quickly with good flow and stable conditions.
Tissue recession or melting: Often caused by alkalinity swings, poor water quality, or pest irritation.
Aiptasia or vermetid snails: Check regularly.
Color fading: May indicate too much light or nutrient starvation.
