Theo, pacu are related to piranha, but their similar appearance is due mostly to mimicry. The younger pacu are excellent red bellied piranha mimics. As pacu grow larger, the piranha mimicry largely disappears.

Looks like fun! I went to a small aquarium in New Orleans Audubon Zoo years ago, and it was enjoyable. We now have the "Aquarium of the Americas" that I must visit some day. It's supposed to be huge and spectacular.
