Clown Triggerfish
Balistoides conspicillum · also called big-spotted triggerfish
Patrolling its stretch of reef with unmistakable confidence, a clown triggerfish flashes a black body covered in bold white polka dots and a yellow net-patterned back, a combination striking enough to make it one of the most recognisable fish on any coral reef, and ornery enough to make most neighbours keep their distance.
Overview
The clown triggerfish, Balistoides conspicillum, is native to ocean and coastal reef habitat across the Indo-Pacific region. Its bold polka-dotted and net-patterned colouring, notoriously aggressive temperament, and locking dorsal spine defence make it one of the most visually iconic and behaviourally formidable fish found on Indo-Pacific reefs.
Beauty with a well-earned reputation
The clown triggerfish’s striking appearance has made it a favourite among aquarium keepers, but its equally well-known aggressive streak means admiration for this fish usually comes paired with a healthy dose of caution.
Status
Least Concern, remaining widespread across suitable reef habitat throughout the Indo-Pacific region.
