Microalgea (Eg. spirulina)
Macroalgea (Eg. seaweed / nori)
Small crustaceans (Krill, mysis, artemia...)
Larger crustaceans (Shrimp, crabs...)
Large polyp stone coral (LPS)
This species likes to eat tubeworms.
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.
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.
This species eats glass anemones (Aiptasia).
But occasionally one finds an individual fish which refuses to eat them.
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.
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.
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.

"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
