Lobsters have a strong flow of water, like new water and living water, go upstream against the water, and like to live in groups.
In the ponds, groups are often clustered around the water intake. In heavy rainy days, the shrimp can reverse the current to the shore for a short stay or escape, and the water environment is not when the water environment is uncomfortable, it will also climb to the shore to inhabit, so the breeding site should have anti-escape fence facilities.

Feed some cockroaches, grasshoppers, crickets and other insects, or feed some lean meat, animal offal, synthetic Arowana feed, etc.
Arowana is a carnivorous animal, in addition to shrimp, the keeper can also feed them some small goldfish, bloodworms, loaches, tadpoles and other live bait, can also be fed some cockroaches, grasshoppers, crickets and other insects, or feed some lean meat, animal offal, etc. These foods are high in protein and fat, which can meet most of the nutrients they need for their daily development.
There are also many synthetic Arowana feeds on the market, which are determined according to the habits of Arowana. When kept in captivity, synthetic feed can also be used as their staple food. However, synthetic feed is not easy to digest, and breeders should pay attention to the amount of feed when feeding.
Precautions for feeding the Arowana
1. Large shrimp must cut off the sharp part of the shrimp to avoid hurting the stomach of the arowana.
2. When raising bait, sterilized containers should be used, and the small shrimp and loaches that you just bought should also be disinfected before they can be fed.
3. The number of each feeding is up to 8 minutes full according to the amount of food of the Arowana.
4. The cockroaches that Arowana love to eat must also be fresh, because we must be vigilant against the damage of pesticides to Arowana.
5. When feeding live loaches, you should also make the loaches faint first, because it is too fresh and easy to hurt the arowana.
6. In the juvenile stage, do not feed whole shrimp to avoid indigestion of the arowana and cause violent death in the juvenile stage.
