Many aquarium keepers consider successful livestock breeding to be the peak of their hobby. The fish have paired up and laid eggs, and the hobbyist has spent countless hours preparing foods for the new fish fry and making sure the water parameters are pristine enough to support the delicate new fish. Unfortunately, not all breeding activity is a welcome sight in an aquarium. Large clams and coral colonies can randomly spew reproductive fluids into the aquarium, which can lead to poor water quality if left unchecked. The eggs and sperm will get eaten by fish and corals, but they can’t keep up with the massive amount of gametes floating around in the water. They will begin to decay rapidly, and the only way to fix the issue is to perform massive consecutive water changes.
