Hi Lyin,
In hatching triop eggs, there are 3 very crucial elements that affects them. The first one is the quality of water, distilled water is highly recommended, the second one is the temperature that range within 22 to 29 degrees centigrade ; and the lighting which is within the range of 12 to 16 hours per day. Flourescent light is highly recommended.
Fluctuations on these elements may result to either prolonged hatching or failure to hatch. Please wait for about 7 to 10 days, as some triop eggs may hatch within that period of time to be sure.
For other related information, please visit and talk to our Pet Care Consultants in all our PLC outlets.
Warm regards,
