Blue Jaw Trigger Female Med

About this fish

Blue Jaw Trigger Female Med is a home saltwater aquarium triggerfish identified as Xanthichthys auromarginatus. It’s a bold, interactive fish known for strong jaws and an alert “big personality,” making it a popular choice for aquarists who want an active centerpiece fish. In practice, a blue jaw trigger is typically kept in a well-established marine tank with live rock for grazing and exploring, and it requires thoughtful tankmate planning because many triggerfish can be aggressive and may eat invertebrates.

• Bold, intelligent behavior with strong-jawed feeding and a noticeable personality
• Best suited to a marine fish setup with live rock and other robust tankmates
• Many triggerfish are aggressive and may prey on invertebrates, so choose companions carefully
• Some species, such as the blue jaw, are often described as calmer than many other triggerfish
• Offer a slow acclimation and a quieter spot in the aquarium so it can settle in
