Reef enthusiast
FAMILY - Ballstidae

SCIENTIFIC NAME - Xanthichthys auromarginatus

COMMON NAME – Bluechin, Blue Throat, Blue Jaw, Gilded

SIZE – 12 in (30.5 cm)

RANGE – Indo-Pacific

MIN. AQUARIUM SIZE – 100 gal (378.5 L)


TEMPERAMENT – Semi-Aggressive

FOODS AND FEEDING - The Bluechin triggerfish is a carnivore and should be fed a wide variety of high quality meaty marine foods. Vegetables should also be offered.


REEF COMPATIBILITY – With caution. As they get older, large specimens may eat invertebrates, but are generally considered reef safe.

CAPTIVE CARE – They may be kept in pairs or small groups as long as there is only one male per tank. Only the males have the blue chin. They are semi-aggressive so they should not be kept with more docile, delicate fish. Larger tanks will keep aggression to a minimum. May go after any hands placed in the tank so caution should be used around this fish.
