Silver arowana is better to keep one silver arowana in a fish tank. Because they have a strong sense of territory, they eat a lot and like to grab food. Therefore, it is better to keep one. However, the number of silver arowana is not only related to their habits, but also related to the size of fish tanks. If the fish tank is large, you can put two or more fish in the fish tank. However, if the space in the fish tank is small, it is necessary to put a fish in the fish tank. So as to prevent them from competing for each other and avoid them fighting and getting hurt because of competing for territory.
2. What size fish tank should silver arowana be raised wellSilver arowana belongs to large ornamental fish, so it is necessary to prepare a fish tank with larger space for them. Therefore, the prepared fish tank is at least 1.5 m long, 0.7 m high and 0.5 m wide. It is best to breed a silver arowana in each fish tank, because they like to grab food and they are larger.
Also note that a cover should be placed on the tank. Because silver arowana is very lively and active, once they jump in the fish tank, they will probably jump out of the fish tank and die due to lack of water and oxygen. Generally speaking, one silver arowana should be cultivated for every liter of water. If the number of arowana is too large, it can also be mixed, but the container volume for breeding them should be larger.
