🐟 Sheep Pacu – (Acnodon normani) – Rare South American Pacu Species for Sale

The Sheep Pacu (Acnodon normani) is a rare and unusual characin from the Amazon Basin, named for its distinctive, human-like teeth that resemble those of a sheep. This powerful, deep-bodied fish is related to other pacus but stays somewhat smaller than the giant Colossoma and Piaractus species, making it slightly more manageable—though still requiring a very large aquarium.

Its unique dentition allows it to crush seeds, nuts, and other hard foods in the wild, while its shimmering silver body and bold vertical bars give it a striking appearance in the aquarium.
