-
Water Quality: They need high pH, alkalinity, and calcium levels, along with low phosphate and nitrate levels.
-
Feeding: They can rely on symbiotic zooxanthellae algae for photosynthesis and may also benefit from supplemental feeding of meaty marine foods like mysis and brine shrimp.

Temperament: Duncanopsammia corals are generally peaceful and can be housed with other non-aggressive corals and invertebrates, provided they have ample space to grow.
