About
Ocellaris clownfish (Amphiprion ocellaris) are the ambassadors of the reef hobby, and almost certainly the fish that introduced more people to saltwater aquariums than any other species. Native to shallow lagoons and coral reefs across the Indo-West Pacific, from the Andaman Sea through Indonesia and the Philippines to Taiwan, these small, boldly patterned fish are instantly recognizable with their orange bodies crossed by white bands edged in black. In the wild, they spend their entire lives in close association with large sea anemones, weaving fearlessly among tentacles that would paralyze most other fish. They are protandrous hermaphrodites, meaning dominant individuals in a group can transition from male to female, and bonded pairs are monogamous and devoted parents. Males actively guard and fan the egg clutches. In the aquarium they do not require an anemone to do well, though when one is present you will see their full territorial personality on display. They can be kept singly, but a bonded pair is far more interesting to watch. Despite their reputation as a beginner fish, their saltwater requirements and territorial nature earn them an advanced care rating, so they are best paired with keepers who understand reef system management. Captive-bred specimens are widely available and are always the better choice over wild-caught fish.
