This video shows one of the many beautiful contrasts of color that this genus possesses. All Dendronephthya species are aposymbiotic, being voracious feeders, absorbing many nutrients in the water, as well as feeding on phytoplankton and/or zooplankton with their polyps, depending on the species. They will also use sweeper tentacles to capture food in the wild. Carnation Corals are difficult to keep, with only advanced aquarists being qualified to own them. Going from the dealer to tank, they often deflate, never to return, then start to decay. They need a constant current and a constant drip of zooplankton and/or phytoplankton to keep them healthy, which in turn can pollute the aquarium.
