This South American family are commonly known
as Parasitic Cats or by the local indigenous
populations as "candiru". Stories
abound on the notoriety of this family due to
their habit of lodging themselves in the gill
cavities of other larger fish and biting the
gill filaments, thereby feeding on the blood.
There has also been instances where they have
entered the human urethra, probably by mistake,
of bathers and mammals urinating under water.
Not
a lot is known of them as aquarium fish and
only experiences with them in a larger group
could bring further information to the catfish
enthusiast.
