OptimalEnvironment Water Optimal Environment Water is a breeding water that can be used to keep saltwater and freshwater fish in the same tank. In the case of eels, it is known that they grow 1.2 times faster than in freshwater and 2.5 times faster than in seawater. Eels grown in water with a favorable environment have a higher fat content and a lower odor than those grown in natural water. The skin is also softer and easier to eat.
