Clown Trigger (Balistoides conspicillum) Care
The Clown Trigger, Balistoides conspicillum, is also known as the Spotted Triggerfish and the Bigspotted Triggerfish. These fish come from the Indo-Pacific region. They have a black body with large white spots on the lower half and a yellow highlights on the mouth, anal fin, dorsal fin, and caudal peduncle.
Triggers are carnivores and require a diet rich in meaty foods, such as brine and mysis shrimp and pieces of high-quality seafood like squid, clams, shrimp, fish, and scallops. One of their favorite foods is live urchins. They will also eat starfish, crabs, shrimp, and small fish in the tank.
Clown Triggers can reach up to 20″ and require an aquarium of at least 300 gallons with plenty of live rock with hiding places. They are quite aggressive and should not be kept with very peaceful, slow-moving fish. They are best kept in fish-only (or fish and coral only) aquarium.
They are considered reef safe “with caution” because although they will not both coral, but will eat invertebrates and smaller fish.
