#chalcidae

This little guy is at my local aquarium and is in the Amazon exhibit with some freshwater rays and red-spotted myleus. They’re a newer addition and haven’t been added to any of the fact sheets yet so I can’t find anything about them! IDK if they’re native to the Amazon or just another freshwater fish that they just added.

Henlo, yes, this is the Tucan Fish (Chalceus erythrurus), family Chalceidae, order Characiforms, found in South America.
