Well established aquarium with algae

These fish should be kept in a well run aquarium where they can "graze" algae from rocks and stones.

If there are insufficient algae on the rocks, it is important to feed more frequently and supplement with algae rich food e.g. Spirulina. 

Hiding places

This species needs good hiding places, for example, between live rocks.

Initially shy

This species can be very shy when first introduced into a new aquarium.

More aggressive fish can be introduced after this species has acclimatized.

Descriptions and further reading
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.
