You can check whether the eggs are fertilized and consider changing the water or adding an extra tank. If the eggs in the tank are transparent, it proves that the eggs in the tank are fertilized eggs.

If the fish you raise will eat the eggs If so, it is best to prepare a new fish tank, put the roe in a fish tank alone, and change the water of the original fish tank. To ensure sufficient oxygen supply, water temperature and other external conditions, wait a few days after the eggs hatch.

If the eggs in the tank are cloudy, they are usually unfertilized eggs. Some unfertilized eggs will be sticky, which will make the water surface of the fish tank turbid and reduce the oxygen content, resulting in suffocation of the Rockwell horns in the original fish tank, affecting growth. At this time, the water should be changed as soon as possible.
