As aquarium fish
These fish normally eat for the most part, coral polyps, therefore problems can arise in captivity when trying to give it an alternative food.
It is therefore essential to be well prepared before acquiring them.
However well prepared, there will be a large percentage, that will die after a short time in captivity.
It may mean having to keep live acropora as food, in order to keep these fish alive whilst they are getting accustomed to alternative types of food.
Requires plenty of space for swimming.
This species revels in swimming and requires an aquarium with ample space.
Lives in a pair
This species can live as a pair (male and female).
This species can be very shy when first introduced into a new aquarium.
More aggressive fish can be introduced after this species has acclimatized.
This species needs good hiding places, for example, between live rocks.
Family description (Monacanthidae)
Filefish (Monacanthidae) have a very characteristic appearance, but whether one likes them or not is a matter of taste.
Some species are suitable for aquaria, although they will occasionally eat a coral or invertebrate. They are therefore not so well suited to coral tanks.
They are often used to fight glass anemones (Aiptasia) and Majano anemones. Pervagor nigrolineatus is especially good at this.
They need peace and quiet from both the aquarist and other fish, when adjusting to the tank life.
Be careful when catching them, as they easily becomes caught in the net.
