 The species preferentially occupies the middle and mid-lower water levels in the wild.Lemon tetras fare best in a planted aquarium, where they should be kept as schooling fishes, allowing them to replicate their wild behaviour as closely as possible.A minimum of six individuals should be kept in an aquarium, though if space allows, a larger number is preferable, as the species exhibits a marked preference for grouping together in large shoals of its own kind where possible.
