I was excited when I heard I may get fry from my Rainbows. I put in watersprite...I remove all snails I can find, and keep water clean. Feeding variety of foods
Check the roots of the Water Sprite for the eggs. The eggs are about 2mm in diameter and clear. They are pretty easy to see. Alternatively, move the adults into a new tank every 2-3 weeks and the babies will hatch out in the previous tank and you will see them swimming around just under the surface.
