Overview:
The Blue Jaw Triggerfish, also known as Xanthichthys auromarginatus, is a vibrant marine species that requires a spacious aquarium of at least 125 gallons to thrive. These fish prefer a well-structured environment with plenty of hiding spots created by live rock formations. The water conditions should be stable, with a temperature range of 72-78°F, a pH of 8.1-8.4, and a salinity of 1.020-1.025. They are known for their peaceful nature compared to other triggerfish, making them a suitable choice for community tanks with the right conditions.

Compatibility:
While Blue Jaw Triggerfish are generally more peaceful than other triggerfish, they can still exhibit territorial behavior, especially in smaller tanks. They are best kept with other semi-aggressive or similarly sized fish to prevent bullying. Suitable tankmates include larger wrasses, tangs, and angelfish. Avoid housing them with small, timid species or invertebrates like shrimp and crabs, as they may become prey. Providing ample space and hiding spots can reduce aggression and promote a harmonious tank environment.

Health and Quarantine:
Blue Jaw Triggerfish are hardy but can be susceptible to common marine diseases such as ich and marine velvet. Quarantining new fish for at least 2-4 weeks before introducing them to the main tank is crucial to prevent disease transmission. Regularly monitor water parameters and perform routine water changes to maintain a clean environment, reducing stress and disease risk. Observing their behavior and appetite can provide early indicators of health issues. If any signs of illness appear, promptly address them with appropriate treatments, such as copper-based medications for parasitic infections.
