The best water temperature for submarine fish is 26 to 30 degrees. When raising submarine fish, it is necessary to ensure the health of the water quality. It is necessary to put an appropriate amount of sea salt in the water, and the diet must also be healthy. Submarine fish are very sensitive to water temperature, and they basically don't move below 25 degrees. When the submarine fish is weak and loses appetite, the water temperature should be raised to 30 degrees, and it will improve immediately.

Submarine fish do not like the environment with large and fast currents, and they like Old water, do not like to change new water. Soda water is used for raising submarine fish, that is, salt water + fresh water, with a specific gravity between 1,002 and 1,018, because submarine fish are fish that grow in the junction of salt and fresh water.
