CHARACIDAE - CHARACINS
A large and diverse family containing some of the smallest species in Paraguay as well as large sport fish such as the Dorado and the infamous Piranhas. Characins can usually be identified by the presence of an "adipose fin", a small fleshy fin situated on the upperside between the dorsal fin and tail.
