Breeding Leopard Danios
- Two fish will form a breeding pair which they often keep for life. If you wish to retain the young, the breeding tank should be empty except for a two inch layer of large (.5- 1 inch in diameter) glass marbles.
- Add the female to the tank and let her settle for about a day before adding the male. When they are both in the tank, adding a few cups of cold water will cause the courtship to begin.
- If conditions are favorable, the female will release her eggs in open water and the male will fertilize. The eggs will then sink to the bottom and fall through the marbles, out of their parents reach.
- The fry will emerge from the marbles after about 7 days. At that time or before, parents should either be removed or kept constantly well fed.
