The Line Spot Triggerfish is a highly sought-after, deepwater triggerfish admired for its refined appearance and comparatively mild temperament. Its silver-gray body is accented with fine horizontal lines and subtle spotting, giving it a clean, elegant look that sets it apart from more aggressive trigger species.
Unlike many triggers, Xanthichthys lineopunctatus is primarily planktivorous, spending most of its time swimming in the water column rather than hunting rock-dwelling invertebrates. This behavior makes it one of the more reef-compatible triggerfish when properly fed, and it typically coexists well with corals and larger, peaceful tank mates.
Best suited for large, established aquariums, the Line Spot Triggerfish is intelligent, active, and visually impressive, making it an excellent choice for experienced aquarists seeking a standout display fish with controlled behavior.
