About

Moenkhausia jamesi is a mid-sized tetra from the Amazonian tributaries of Ecuador and Peru. Its body is pale golden with clearly etched scale outlines giving it a delicate, embossed appearance, and it bears a characteristic black triangular spot at the caudal peduncle. While not flashy, its clean, elegant form is an excellent complement to more brightly colored species in a South American community aquarium. It is a calm, hardy fish that thrives in groups and accepts most aquarium foods without difficulty. Its adaptability and peaceful temperament make it a reliable and low-maintenance community species suitable for a range of skill levels.
