Feature Article: Experimental aquaculture of Dendronephthya corals

By Tim Wijgerde, Ph.D. on Jul 22, 2015 at 09:00 AM

Back in 2005 I first read about Dendronephthya corals, notorious for being difficult to maintain in aquaria. Lacking zooxanthellae, these corals require plankton to stay healthy. In the following years, I read up on the scientific literature, and toyed with the idea of setting up an aquarium specifically designed for Dendronephthya. This led to the launch of a crowd funding project on Indiegogo, to acquire funds for the development of a culture protocol for Dendronephthya corals. Although insufficient funds were gathered to fully develop an aquaculture system and culture protocol, two preliminary experiments were conducted. In this article, I will present the results of these experiments, and provide future directions for research. This may help aquarists to keep pushing the frontier of coral husbandry and aquaculture.
