Duncan Corals

Scientific Name: Duncanopsammia Axifuga

Common Name: Duncan Coral, Whisker Coral, Daisy Coral,

Type of Coral: LPS  (Large Polyp Stony Coral)

Lighting: Moderate

Flow: Moderate

Care Level: Moderate

Temperament: Peaceful to Semi-Aggressive

 

Appearance

Duncan corals will have a base that consists of an calcified skeleton structure covered in a green or pink colored thin layer of flesh.  At the end of this structure will be individual fleshy heads with long polyps extending around the edges and a mouth in the center of the head.  The heads will be a similar color to the base.

 

Water Conditions

The below link highlights typical water conditions Duncan corals, as with most LPS, will require.  As this is a moderately difficult coral to keep, you should ensure your dKH, Cal and Mag levels are maintained at all times with minimal nitrate and phosphate levels.  As this coral also has a calcified skeleton, it will consume calcium from your water.  In set-ups with a good amount of LPS corals, it is not uncommon to have to dose dKH and Cal in order to keep the water parameters in line.  With only a few LPS corals, a good water change schedule may be enough to maintain your parameters.  In addition to the article in the below link, this coral can also benefit from maintaining strontium levels if you do not have a good water change routine using a very good quality salt.

General Information

Duncan corals, as with all other LPS corals, should be added to mature aquariums. Provided all their requirements are met, they can grow to a very large colony within a few short years.  Unless you are planning to move or frag your duncan coral, you should give it as much as 20 inches of space in your tank.

The Duncan coral will release sweeper / feeder tentacles from its heads to collect food.  This will mostly happen when the tanks lights are off.  These tentacles can also sting and damage or kill other corals within reach, which is how the duncan coral will defend itself.  What makes the duncan coral more peaceful than most LPS coral is that its sweeper tentacles are much shorter in comparison only measuring a few inches in length.

Although the duncan coral will get what it needs from the lighting in your tank, it can also benefit from micro plankton or manual feeding of small pcs of meaty foods placed directly on the mouths at the center of each head.  Although manual feedings are not required, it will help to accelerate growth.

As with all corals, the exterior slime coating can be a skin irritant or even highly toxic to humans so please, handle all corals with care.  I would recommend wearing rubber gloves whenever you handle corals

 

Fragging

Duncan corals can be fragged with very good success.
