Fish friends with some experience know that anti-swordfish is notoriously grumpy. This kind of fish is very territorial and aggressive, so they can't be mixed with other fish, and it is best to keep them alone. They have very strict requirements on water quality. The water quality is too new or too old, which is bad for their health. The number of water changes should be more. Because their feces are deposited at the bottom of the aquarium, they will decompose some ammonia, and they will form nitric acid in the water, which is a fatal threat to the health of swordfish. This is the reason why many fish friends have died in large areas of anti-swordfish. This kind of fish is still difficult to raise. Without skills, it is difficult to feed them.

1. Water quality: When raising, the pH value of water should be adjusted to a weakly alkaline state of 7.0-8.0, and the hardness of water is better. When raising, change water more often. Reducing nitrate content in water is beneficial to ensure their healthy growth.

2. Feeding: They are carnivorous fish, and prefer animal bait and fresh live bait. Bait such as bumper worms and red worms can be selected for feeding.

3. Environment: They are typical daytime and nocturnal ornamental fish, and they will come out to prey at night. Some rocks or caves can be placed at the bottom of the aquarium to provide shelter for them.
