Hoplias aimara or freshwater Wolf Fish, is a species found in the rivers of South America; mainly in Brazil, Guyana, Suriname and Venezuela. Hoplias aimara is often found in counter current zones of principal rivers and creeks. This fish is mainly an ambush predator of fish but also feeds opportunistically on other animals that fall into the water such as terrestrial invertebrates. Seems that this fish can reach the 80 pound - 40 kilos and 47 inch - 120 cm in lenght but bigger fishes was caught with net in the past decade. Pictures 3 and 4 courtesy of Yudhistira Prasetyo.

DISTRIBUTION: South America
MAX SIZE: 80 lb / 40 kg (?)

Hoplias aimara is one of the most aggresive fishes in Rivers and the most aggresive fish in captivity always ready to attack the person that gets too close to the tank, it is very territorial it had attacked humans defending its territory in the wild, fishermen avoid them because they say that they have destroyed their nets with their powerful jaws when I asked them if they could catch one for my aquarium, that is the reason the few ones you see in aquariums are very small specimens.
