Hemmm, if I were to give you advice, you should move the seeds after the mother's behavior becomes weak. Later, the fish eggs will hatch in about 2 to 3 days. However, egg hatching may depend on the water temperature.

Eggs may hatch faster if the tank water is warmer. If the water temperature is less than 78°F, the eggs will take longer to hatch. Meanwhile, if the temperature is 80°F, it is perfect for hatching black anglefish eggs.
