Like the sergeantfish, the puller, aka as chromis and the damselfish,  the anemonefish is a member of the family of the Pomacentridae. This family is well-represented in the subtropical waters of the Red Sea and boasts ten species that are endemic to the Red Sea. The intriguing anemonefish or clownfish,, or Nemo, is your Red Sea ‘poster reef fish’ and deserves special praise.

The adorable Red Sea anemonefish lives in harmony and in symbiosis with anemones, seeking shelter in its urticating tentacles. There mutualistic and reciprocal relationship is like a twinned pairing between anemone and the Red Sea clownfish. Their bond is truly  a classic case of symbiosis. The anemone and the clownfish, albeit two organisms, live in close beneficial harmony . The essence of their interacting lies in the tentacles of the anemone protecting the clownfish from predators. In turn, the clownfish’s movements within the tentacles of the anemone, causes water circulating and hence increases oxygen flow. It has also been suggested that the anemone feeds on the fish’s waste material.

The clownfish never survives without an anemone host. It is always protected from its host’s stinging cells and ‘chemical signature’ by its own mucus. Large anemones can be host to a pair of anemonefish, accompanied by small juveniles. The clownfish starts life as a male and eventually turns female. In scientific terms we call this protandrous hermaphrodites. In the event of lacking females, the largest male will transform. The anemonefish finds zooplankton pretty pleasing to the palette and has a specific liking for filamentous algae and copepods.
