TSA Blue Sea Duncan Coral FAQ's

Why does my Blue Sea Duncan Coral open fully some days and stay tight on others?

Day-to-day expansion swings are normal, but big changes point to flow, chemistry, or harassment. Aim for gentle, oscillating flow; too direct will keep polyps tight. Keep alkalinity steady (8–9 dKH), nitrate 5–15 ppm, and avoid sudden PAR jumps. Peppermint/cleaner shrimp or nippy fish can cause retraction by stealing food. Target-feed after lights ramp up to encourage confident extension.

How do Duncans actually grow—head splitting or new buds—and how can I speed branching?

Duncanopsammia axifuga typically buds new heads from the sides of its branching skeleton rather than splitting a single mouth. Frequent, small meaty feedings (e.g., mysis) 2–3x weekly accelerate budding. Maintain stable Ca/Alk/Mg and PAR around 80–150. Slightly higher nutrients promote tissue growth. Provide space so new branches don’t shade or press against rock.

My Duncan’s green centers faded and the rim browned—what drives these color shifts?

Color shifts reflect light spectrum, PAR, and nutrient balance. Too little PAR or very low nutrients dull fluorescence; too much sudden light can bleach. Target PAR 80–150 with a blue-leaning spectrum, and avoid zero-nutrient conditions. Increase feeding rather than dosing trace elements blindly. Make lighting changes over 2–3 weeks. Improved polyp inflation often precedes color rebounds.

What causes base recession or polyp bailout, and how can I save the colony?

Triggers include rapid salinity/temp swings, strong laminar flow, bacterial issues (e.g., brown jelly), or fish nips. If tissue recedes, cut above the affected skeleton to healthy heads, dip in iodine/antibacterial solution, and place in moderate, turbulent flow with reduced light for a week. Siphon any jelly promptly. Re-stabilize parameters and feed lightly once extension returns.
