Like other clownfish/anemonefish, well-known for mutualistic relationships w/ anemones. Sea anemone protects clownfish from predators as well as providing food through scraps left from anemone’s meal & dead anemone tentacles. In return, clownfish defend anemone fiercely from predators/intruding clownfish. Unlike many clownfish, they can thrive w/o host anemone & utilize coral host if anemone not available.
Sometimes mistaken for Australian Clownfish, Cinnamon Clownfish/Red-and-Black Anemonefish, & Red Saddleback Anemonefish.
Pairs/colonies extremely territorial, often fighting to the death w/ intruders. Females will especially fight to the death.
Maturity determined more by size than age.
Spawning occurs during full moon.
After hatching, fry drift for around 16 days in plankton-rich waters.
Clownfish only take anemones not filled by other clownfish.
Females release anything from 100-1,000 eggs.
Sometimes hybridize w/ Cinnamon & Fire Clownfish.
