As aquarium fish
This species likes to eat tubeworms.
Can be a threat towards small crustaceans
This species can be a threat towards small crustaceans, e.g. small shrimp.
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.
Eats glass anemones (Aiptasia)
This species eats glass anemones (Aiptasia).
But occasionally one finds an individual fish which refuses to eat them.
This species is very shy and docile, so one should be careful when keeping it with more aggressive fish.
Over time this species can lose some of its colour when the food does not contain sufficient vitamins.
It pays therefore, to use a some type of enriched food, or one, specific to this species.
This species needs good hiding places, for example, between live rocks.
In the beginning, feeding these fish can be problematic.
Attaching a shrimp to a coral, which can lure the fish into eating is one way to achieve this.
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.
