You could call it the Reef Triggerfish, Vi-line Humu Humu, Rectangular Triggerfish, or the Wedge-tail Triggerfish. All these names represent the Reef Triggerfish which can be found across the high seas and is popular among the diving community and aquarium enthusiasts alike.
This fish is very popular in the state of Hawaii. The fish inherits its Humu Humu Hawaiian name due to the fact that it has a pig-like snout which is often used to root around the coral reefs.
In the wild, the Triggerfish is most frequent along the outer edges of coral reefs found in the Red Sea, Central, and Western Pacific.
The general appearance of Triggerfish
The fish has a tan body which is also characterized by dark bands. It has blue lips, blue/black strips which cross the eyes and a black wedge which is situated at the base of the caudal fin. This area is outlined in brown and yellow colors respectively.
It should also be noted that this fish is very maneuverable, and changes directions very fast. Catching it nearly seems impossible if you’re not aware of these tricks.
Equipped with a large spine in the front, it can make use of that feature to lock itself between rocks and coral where it can sleep safely from predators. What is more, this fish has been known to sleep on its sides too.
Triggerfish when in captivity
First of all, this fish is fairly easy to keep. But you should only know that it’s not a community fish – that is, it can’t exist in harmony with other fish due to the fact that it’s a territorial species.
Unlike the Clown Trigger, the Reef Triggerfish is less aggressive and is the best choice for anyone wanting to keep fish of this species.
The aquarium should contain up to 140 gallons of water, but no less than 75 gallons. What is more, the keeper should allow plenty of areas to hide and also swim freely in the water.
In the wild seas, this fish feeds on wild algae and invertebrates. But when in captivity, it can also feed on regular fish food which consists of live, frozen, or flaked foods. This may include shrimps, squid, sea urchins, small pieces of fish, small fish, starfish, and anything in between.
To make sure that they are getting enough nutrients from food, the keeper should also supplement their diet with algae, spirulina, and dried seaweed. However, it should be noted that they can be aggressive during feeding time. They can bite fingers when care is not exercised. They will even end up disturbing items inside the aquarium.
Reef Triggerfish lay eggs like most fishes. However, they are never bred in captivity. Keep this in mind.
Other things to note
Only one fish may be kept per aquarium, although it is still being experimented whether this fish can co-exist with similar species like the Redtoothed Triggerfish. It is also thought that this fish might exist with large basses, large surgeon fish, groupers, aggressive eels, puffers, and lion fish. But they cannot certainly co-exist with invertebrates.
