This is a very varied group of fish, as demonstrated by those species we show pictured here. They are mostly easy to keep in the aquarium, and do not normally give any particular problems. Good feeding is important (as it is with any aquarium fish!) and will minimise any propensity to anti-social behaviour.
The Tasseled Filefish (chaetodermis penicilligera) is one of the more peculiar marine fish, with the ornamental extensions breaking up the outline of the body shape. It can grow quite large, but is usually a peaceful species.
The Orange Spotted Filefish (oxymonacanthus longirostris) is a very peaceful fish that needs to be housed in a peaceful environment for success. It is a good choice of companion in a seahorse tank, or an invertebrate “reef” aquarium with only very quiet other species.
