At a glance the quick version
Looks how to spot one
Personality what they are like
A bold, territorial fish once it matures, quick to defend its home and not keen on other clownfish. Some adults are even known to nip at the hand that tends the tank.234
Daily activity how busy a day looks
Spends its day around a host anemone or chosen coral, staying in a defined home area.24
Grooming and care the hands-on bits
A fully marine fish rated easy to care for. Suggested aquarium water: about 22 to 26 °C (72 to 78 °F), pH 8.1 to 8.4, carbonate hardness 8 to 12 dKH and specific gravity 1.020 to 1.025. It does well without an anemone and may adopt a coral instead.42
Home where they are happiest
A saltwater aquarium of at least about 114 L (30 US gallons). In the wild it lives on lagoon reefs and in bays at about 1 to 12 m, mainly with the bubble-tip anemone.412
Food basics what goes in the bowl
An omnivore that takes most meaty and plant-based foods, such as dried algae, mysis shrimp and brine shrimp.241
Company who they like around
The story where it all began
