Not Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Indo-Pacific Ocean: Red Sea to Natal South Africa, east to Indonesia and to Tuamoto Islands and north to Southern Japan.
Size: 24 inches (60 cm)
Natural Environment: Inhabits inshore coral reef areas and estuaries, and is often found on lagoon slopes and floor areas, and sometimes where mud and silt collect. Seeks caves in the reef structure to hide or rest during evening hours. Feeds on coral tips, urchins, crustaceans, mollusks, and tunicates.
General Husbandry: Has a yellowish whitish face and crosshatched greyish body with its blackish dorsal and anal fins edged in yellow, as are the forward edges of the tail. Not often seen in the trade, simply because its somewhat drab, one of the largest in the genus, and also one of the more aggressive triggerfish. Furthermore, it becomes even more belligerent as it grows older and larger.
When maintained in the home aquarium, it requires 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. Keep in mind they are not reef safe, as they will eat small fish, ornamental shrimp, snails, urchins and worms such as feather dusters and nip various corals.
Definitely a large and aggressive species, and should be maintained with larger more aggressive fish/those that can defend themselves, such as moray eels, snappers, angelfish and tangs, yet not lionfish, as they are too slow moving and a target for fin nipping. May also re-aquascape your aquarium to its liking 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! As to its environmental needs, provide enough rocky caves for it to hide or sleep in. 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: Pseudobalistes
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.
