 Temperature range for the species is 21 °C to 28 °C, though the species is capable of withstanding water temperatures up to 32 °C for considerable periods of time if the water is well oxygenated.Aeration and good quality filtration should be provided for this fish (and indeed for all aquarium fishes) though the fish is sufficiently hardy to cope with aquarium equipment failures provided these are attended to upon discovery.Extremes of high pH (8.0 or higher) and hardness should be avoided, as these will subject the Lemon Tetra to potentially life-threatening stress.
