Duncan Coral

Duncan coral (Duncanopsammia axifuga, family Dendrophylliidae) is the sole species of its genus, native to reef slopes of northwestern Australia and southern Japan. Colonies produce numerous large polyps (2–4 cm diameter) in shades of green, brown, and purple that extend multiple tentacles in a whisker-like display—hence its alternative common name, "whisker coral." Duncan coral is straightforward to keep under low to moderate lighting (100–200 PAR) with gentle indirect flow. It responds eagerly to target feeding of brine shrimp or small meaty foods one to two times per week, rewarding hobbyists with rapid colony expansion and easy fragging.
