This species likes to eat tubeworms.
This species can be a threat towards small crustaceans, e.g. small shrimp.
This species can be fastidious and in an aquarium it can be very difficult to get them to eat sufficiently.
This fish requires feeding several times a day, especially when newly added.
When the fish can find its natural food in the aquarium it requires less frequent feeding.
This species needs good hiding places, for example, between live rocks.
This species is very shy and docile, so one should be careful when keeping it with more aggressive fish.
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.
