Can fish eggs hatch on their own?
This is their natural way of surviving in the environment. As for the hatching time, it mainly depends on the temperature in the aquarium or pond.

How do you prevent fungus from growing on fish eggs?
So a good strategy to prevent fungus is to lower the pH of the breeding tank. This can easily be done with aquarium chemicals that lower pH, or you can use one of the Blackwater Extract liquids to accomplish the same thing, which has the added advantage of adding organic acids that may further inhibit fungus growth.
How do angel fish fertilize their eggs?
Once the spawning site is clean, the female will lay her sticky eggs row by row, and the male angelfish will brush over the eggs to fertilize them. Angelfish will make sure to aerate the eggs to get oxygen to them and they’ll continuously guard and clean the eggs.
What is the lifespan of fish?
