- Commonly known as the Rectangle Triggerfish or Humuhumu Triggerfish.
- Native to the Indo-Pacific region, often found in coral reef environments.
- Recognized for its bold markings, including a rectangular pattern and contrasting colors.
- A hardy and active species known for its intelligence and strong personality.
Feeding
- Omnivorous diet, consuming a mix of meaty foods, algae, and small invertebrates.
- Accepts a variety of foods, including shrimp, squid, clams, and marine pellets.
- Requires a balanced diet to maintain vibrant coloration and overall health.
- May exhibit natural foraging behavior, rearranging substrate and rocks in search of food.
Habitat
- Typically found in coral reefs and sandy lagoons with plenty of hiding spots.
- Prefers stable water conditions with moderate to strong water movement.
- Requires an aquarium with live rock and secure structures for shelter.
- Best kept in an environment that allows for both open swimming space and hiding areas.
Fish Care
- Optimal water temperature: 74-80°F (23-27°C).
- Ideal pH level: 8.1-8.4, with a specific gravity of 1.020-1.025.
- Requires strong filtration and regular water changes to maintain high water quality.
- Can be aggressive toward tank mates, especially if space is limited.
- Providing enrichment, such as varied diet and structures to explore, reduces stress and aggression.
Compatibility
- Generally aggressive and best suited for tanks with similarly robust species.
- Compatible with large, semi-aggressive fish such as tangs and angelfish.
- Should not be housed with small, delicate fish or slow-moving invertebrates.
- May become territorial, especially as it matures.
Aquarium Behavior
- Highly active swimmer that patrols its territory.
