Masked Triggerfish

(Sufflamen fraenatum)

Sufflamen Triggerfish should be added to well established aquariums with plenty of room to swim. Plenty of rock work with caves and crevices should be provided for hiding. Triggerfish are known to turnover rocks, rubble, benthic invertebrates and corals. Provide a sand bed with rubble and seashells to turnover while hunting for prey. Triggerfish are carnivores feeding on small fish, starfish, crabs, shrimp, snails and urchins. They are capable of breaking off the spines of urchins and blowing water to turnover urchins and attacking the underside. They are hardy and beautiful but quite aggressive, Triggerfish have even been known to attack divers when to close in the wild. A diet of meaty based foods should be provided, the addition of algae based foods such as Spirulina may benefit Sufflamen Triggers health. May loose coloration if not adequately fed. Triggerfish should be kept singly or mated pairs as they can be quite aggressive.

Masked Triggerfish are also sometimes known as the Bridled, Brown or Starry Triggerfish. Rarely seen in the aquarium trade. There are slight color difference between the juvenile and adult Masked Triggerfish. Juvenile Masked Triggerfish are a tan color with irregular horizontal black stripes while the adult has a lighter tan and a white face and a yellow stripe at the corner of its mouth. Masked Triggerfish can grow to slightly over 14".

We recommend a minimum aquarium size of 100 gallons or larger for this species.
