"‎Candiru (English and Portuguese) or candirú (Spanish), also known as canero or toothpick fish, are parasitic freshwater catfish of a number of genera in the family Trichomycteridae. They are found in the Amazon River and have a reputation among the natives as the most feared fish in its waters, even over piranha.[1] They are eel-shaped and translucent, making them almost impossible to see in the water. Some species have been known to grow to a size of 6 inches (~15 cm) in length." -- wikipedia

BTW, that's much bigger than any known exodon according to wiki - "
The bucktooth tetra (Exodon paradoxus) is the only member of the genus Exodon and is a freshwater fish of the characin family (family Characidae) of order Characiformes. It is native to South America. Though first described in 1845, it was not imported and distributed by the aquarium trade until 1932.
This species is of typical elongated tetra appearance; it is light tan in appearance with two distinct black spots (one before the tail and another below the dorsal fin). The dorsal fin is bright red. The name is quite contradictory of the actual fish however, with Bucktooth tetras showing no signs of actual teeth. It grows to a maximum overall length of approximately 12 cm (4.7 in)." - Wikipedia
