The Clown Triggerfish (Balistoides conspicillum) is a striking and charismatic saltwater species known for its bold black-and-white spotted body, yellow snout, and vibrant personality. Native to coral reefs across the Indo-Pacific, this fish is intelligent, territorial, and best suited for large, well-established marine aquariums. It requires plenty of swimming space, secure rock structures for hiding, and excellent water quality. Clown Triggerfish are carnivorous, feeding on meaty foods such as shrimp, squid, clams, and other crustaceans, and should be fed a varied diet to maintain health and coloration. Due to their aggressive nature, they are best kept singly or with similarly robust tankmates in aquariums of 125 gallons or more. Regular maintenance and stable water parameters are key to keeping this species healthy and thriving.
