 Temperature should be slowly raised over a period of a few days to 28 °C, the pair conditioned with copious quantities of live foods if possible, and the aquarium should be sited so as to receive illumination by morning sunshine, as this is a well-documented spawning stimulus for the lemon tetra.Parent fishes should be removed from the breeding aquarium and returned to the main aquarium once spawning is complete.Sometimes, best results are obtained by using two males with one female.
