Habitat
The lemon tetra inhabits clear waters with a modest to moderate current flow, remaining in shallower waters in close proximity to stands of aquatic plants. The water chemistry is slightly acidic, and the waters are relatively mineral-deficient. Lemon tetras congregate in their chosen waters in large shoals, numbering several thousand individuals, where the black and yellow colouration becomes disruptive from the standpoint of predatory fish species attempting to track an individual fish. The fishes are capable of moving at speed when required, and in a shoal the fishes will, when danger threatens, weave in and out of each other, adding to the visual confusion for a predator. The species preferentially occupies the middle and mid-lower water levels in the wild.
