Commonly known as whisker coral or daisy coral, Duncanopsammia is considered rare in the United States, but a common addition to Australian coral reefs. Usually found in deeper water near sandy substrate, it is very adaptable to varying lighting conditions.
The color of Duncan can vary from gray-pink to light green on the tentacles, a pink to intense blue-green on the oral disc, and brown to bright green on the corallites. The size of the polyps (including the tentacles) can be up to approximately 4.5 cm across. Duncanopsammia is a fast grower if given the right conditions.
Duncanopsammia are a popular addition to home or office saltwater tanks. They require low to medium lighting, and low to medium water flow. Feeding tentacles appear during the evening ad while exposed, will feed on meaty foods such as brine shrimp or micro-plankton. For continued health, it will also require the addition of strontium, calcium, and other trace elements to the water in the tank.
Softer corals can be more delicate than their stony-type, harder counterparts. When placing Duncanopsammia in a tank, it’s important to make sure its secure, and will not be knocked over. It is not an outwardly aggressive coral, but should be placed with plenty of space between itself and other corals, because it can expand twice its size during the day. Make sure it is secure, so it will not be knocked over, which may damage the skin and cause an infection.
Propagation of the Duncanopsammia is as easy as cutting the ‘stem’ of the coral to separate the polyps. As this coral grows upwards it will not attach itself properly to reef structures. If your coral is in a tank, it is best to attach it using aquarium putty to ensure its safety.
This type of coral is very beautiful to look at. While it does exist in reef structures throughout the world, its delicate nature often prevents it from being plentiful in an ocean atmosphere, unless the conditions are exactly right. It can be more expensive to purchase than other types of coral, but the beauty that the Duncanopsammia brings to saltwater fish tanks is well worth the price. Its delicate beauty and array of colors make it an aquarium enthusiast favorite.
