 In a planted aquarium, the Lemon Tetra displays more vivid colouration - juvenile specimens in bare dealer aquaria usually appear 'washed out' in appearance and do not show the full splendour of which this species is capable.The aquarium for this species should be furnished with plant thickets interspersed with open swimming areas where the fishes can display to each other.Suitable companions in an aquarium include other tetra species, small barbs, small danios, small rasboras, "Corydoras" and "Otocinclus" catfishes, and in aquaria where space allows, certain species of dwarf cichlid such as the smaller "Apistogramma" species.
