Care
Yellowmargin Triggerfish require a spacious tank with plenty of room to swim and areas to hide. They are known to be aggressive, particularly during breeding season, and should not be housed with small or docile fish. A varied diet of meaty foods such as shrimp, squid, and clams, supplemented with high-quality pellets, will keep them healthy and vibrant.
Reproduction
In the wild, Yellowmargin Triggerfish are solitary nesters. Males prepare and guard a nest on the ocean floor where females lay eggs. In the aquarium, breeding is rare, but environmental enrichment and stable conditions may encourage spawning behavior.
Habitat
Yellowmargin Triggerfish are found in the Indo-Pacific region, from East Africa to the Hawaiian Islands, and from Japan to Australia. They inhabit lagoons and outer reef slopes, typically at depths of 10 to 75 meters. They prefer areas with sandy bottoms and coral outcrops where they can forage for food and take refuge.
