Care

Queen Triggerfish require a spacious aquarium with plenty of room to swim and areas to hide. They are known to be somewhat aggressive, particularly towards smaller fish and invertebrates, so careful consideration should be given to tank mates. A varied diet of meaty foods, including shrimp, squid, and fish, is essential for their health.

Reproduction

In the wild, Queen Triggerfish are solitary nesters. Males court females and, after spawning, the females guard the nest aggressively. In the aquarium setting, breeding is rare, but environmental enrichment and a well-maintained tank can encourage natural behaviors.

Habitat

Native to the Atlantic Ocean, the Queen Triggerfish is commonly found in coral reefs, seagrass beds, and sandy areas. They are adept at hunting and often use their strong jaws to flip over sea urchins and other prey. Their natural range extends from Canada to Brazil, including the Gulf of Mexico and the Caribbean Sea.
