Duncan Coral Common names: duncans, whisker coral, daisy coral Difficulty Level: Duncans are very much like most LPS having a pretty good tolerance to most things. They do however thrive better with stable alkalinity and feedings. Feeding: Duncans are extremely aggressive eaters with very capable tentacles. They will easily catch and consume most food types including frozen, liquid and even pellets. Take care as their feeding aggression can sometimes be taken out on neighboring corals. Lighting (Level 3 to 5): Duncans will thrive in a wide range of lighting. As with most hard corals, bleaching is a concern, so always acclimate by starting them lower in the tank and slowly move them up to your desired location. Waterflow: Moderate to strong water flow is important. Placement: Duncans are very aggressive, so be careful to give them plenty of space. General: Duncans grow much faster with frequent feedings. They can be easily fragged like most euphyllia species by breaking heads off at the base of branches.
