Trichomycteridae = ( trick oh mick TARE id dee ) 

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.
