If the fish tank is covered, because it is isolated from the outside air, it will be slightly worse in terms of dissolved oxygen, and it is not convenient to add various equipment, such as filtration, oxygen pump, etc. At the same time, if you want to change the water, it is not convenient to have a lid. Without a lid, there will be no problem in this respect, whether it is to change water or trim water plants, etc. Are very convenient, but also increased the risk of fish jumping tank.
1. Prevent jumping: The biggest advantage of adding a cover to the fish tank is to prevent the fish from jumping. There are many reasons for tank jumping, such as water quality or water temperature discomfort, low dissolved oxygen in water, and some species problems, some fish have the habit of tank jumping, so in order to avoid it jumping out, you can add a lid.
2. Keep the water temperature: If you are raising tropical fish, the cover of the fish tank is still necessary. The purpose of doing so is to facilitate temperature control. Because tropical fish on the temperature requirements are relatively high, generally to maintain between 20-30 ℃, if the temperature changes, the health of the fish is very harmful.
3. Light concentration: After the fish tank has a cover, the light can be more concentrated, but only if there is a special lamp in the tank. Of course, if there is no cover, it can also receive sunlight, but long-term exposure to sunlight will also increase the risk of algae explosion, endangering the survival of fish.
