HusbandryVery special thanks for the first photo of Cupressopathes pumila (Brook, 1889) to Marzia Bo, Ph.D. from Italy!
Dr. Bo has taken this photo in the Bunaken Marine Park in North Sulawesi, Indonesia, between 20 and 30 m depth, the water temperature was around 26 °C.
Black corals normaly feed on zooplankton, but not exclusively!
Have a brief look to the publications underneath this information:
