Peat filtered water makes for the best results. After conditioning a pair on live foods for a few weeks, introduce the pair into the breeding tank during the evening. The pair should spawn within two or three days. If the pair does not spawn within three days, try the process over again. 120-150 eggs are dropped in plants and on the bottom. The fry hatch in 20 to 25 hours. Feed the young crushed flakes and paramecia and Rotifers. After about 15 days, the young develop the characteristic orange stripe.
