Not Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Indo-West Pacific Ocean: East Africa south to Chalumna River South Africa, east to Samoa, north to Southern Japan, and south to Lord Howe Island.
Size: 12 inches (30 cm)
Natural Environment: Inhabits coastal lagoons to outer reefs walls and often found where silt collects or at the base of outer reef walls at depths from 4 - 100 feet (1 - 30 m). Seeks caves or coral branches to hide or rest during evening hours. Feeds on crabs, urchins, crustaceans, mollusks, tunicates, and worms.
General Husbandry: In general, an extremely hardy species having a brownish black body with a somewhat bluish frontal belly and mouth area, a yellow vertical stripe from just aft of the eye to the base of the pectoral fins, and a yellow tail trimmed in white.
In the home aquarium, they require a meaty diet, e.g., chopped fish, shrimp, squid, and clam flesh, and/or meaty type frozen carnivore foods with two or three feedings per day highly recommended. As to its environmental needs, provide enough rocky caves for it to hide or sleep in.
Can only be maintained with larger more aggressive fish, such as large moray eels, snappers, angelfish, tangs or other larger fish that can defend themselves, yet not lionfish, as they are too slow moving and a target for fin nipping. May also re-aquascape your aquarium and make a mess of the sandbed due to its constant searching for infauna/invertebrates. Will also bite the hand that feeds it, so do not place your hands in the aquarium! Keep in mind that generally its recommended not more than one triggerfish be kept per aquarium unless a mated pair, and furthermore, that it be the last fish to be placed into the aquarium.
Taxonomy:
Order: Tetraodontiformes
Suborder: Tetraodontoidei
Family: Balistidae
Genus: Sufflamen
FYI: Their common name, triggerfish, comes from their ability to lock and unlock their first dorsal fin. This fin is normally retracted and carried in a groove on the upper body. When frightened, the fish will dart into a crevice or branch of coral and raise this trigger-like fin, securely locking itself into its place of protection.
They should be housed with small pieces of seashells since they like to bite on them or turn them over in the search of prey. Better these shells than other aquarium decor. It also helps keep their teeth worn-down, which actually could get too long and pointed and cause them some difficulty in feeding.
In general, triggerfish are like angelfish and surgeonfishes, as they have laterally compressed bodies with small mouths with strong jaws and chisel-like teeth for crushing hard-shelled prey. However, eyes are set back and located high on their large head to avoid damage when feeding on urchins, one of their favorite foods.
Especially fond of live urchins, which they turn over with jets of water from their mouth, then consume their meaty unprotected bottom areas.
Even though specimen and confines specific, those in the genera Balistes, Balistoides, Pseudobalistes, Rhinecanthus, and Sufflamen are generally thought of as the most aggressive in the Triggerfish family. Those in the Melichthys, Odonus and Xanthichthys genera are more suitable community fish candidates, yet all are not trust worthy when it comes to invertebrates as mentioned above.
