Once the eggs hatched I removed the larvae and placed them in a plastic container which I floated in the main tank to keep the temperature stable. This also makes it easy for me to change the water. The larvae are very small at this stage and you can clearly see the yolk sacs. The eggs hatched over a period of a few days. By day 4 about 25 eggs had hatched and there are still 10-12 left in the glass container.
