Red swordfish can produce 3-3 larvae at a time

Red swordfish should choose a larger aquarium when breeding, and keep the water temperature at 24-26 degrees Celsius. PH8, and then put the fish in the ratio of 1 male to 1-3 females. After the fish is in estrus, the abdomen of the female fish gradually expands, and the male fish is not short of chasing the female fish at this time. When the male fish's adapter is inserted into the female fish's reproductive hole, the sperm is discharged for in-vivo fertilization. When the fetal spots of the female fish become large and black and the anus protrudes, they can be fished into another aquarium to give birth.

after giving birth, the female fish should be fished out immediately to avoid eating the larvae. Or plastic sheets should be enclosed into a funnel-shaped partition wall and intruded into the water, and the female fish giving birth should be placed in the funnel, so that the female fish will fall into the water outside the funnel from the cavity under the funnel after giving birth, and the female fish will not be able to eat the larvae.

The female swordfish is born once every 4-6 weeks, which is influenced by the age of the female fish and the proportion of the male fish. It can produce 3-3 fish larvae at a time. During breeding, it should be noted that the number of fish kept in the same nest should not exceed the second generation, so as to avoid the species degradation caused by continuous inbreeding, which will make the fish body of the offspring smaller and smaller, and the dorsal fin shorter and narrower. It is best to introduce the same species of fish for purposeful distant hybridization to prevent the degeneration of sub-species and achieve the purpose of improving species. But the life span of red swordfish is very short, generally only 2-3 years.

The culture method is as follows:

Prepare a fish tank, the size of which depends on the number of red swordfish, and try to make the fish have more room to move. When raising red swordfish, it is best to control the water temperature at about 25 -28 degrees.

Red swordfish will concentrate near the water surface when lacking oxygen. At this time, you can turn on the oxygen machine to supply oxygen. If there is no oxygen machine, change some water for the fish, and find a suction pipe to suck the dirty things at the bottom of the tank. Just change 1/3 or 1/2 of the water. If you change too much, the fish will not adapt. Clear water does not mean that there is oxygen in the water. Try not to touch the fish when absorbing or adding water, so as not to hurt the fish.

The male and female swordfish should be distinguished, and the male and female swordfish should be distinguished by their tails: those with swords on their tails are male and those with round tails are female. The tail of a small fish is round, and when he grows up, the male fish will grow a sword.

Red swords have beautiful tails, but they also like to chase and bite, often biting their tails, so it is best not to raise other aggressive fish, such as tiger skins.

Red swordfish can be fed with professional fish food, and bread crumbs can also be used. Red swordfish is not very selective.

The female swordfish is born once every 4-6 weeks, which is influenced by the age of the female fish and the proportion of the male fish. It can produce 3-3 fish larvae at a time. During breeding, it should be noted that the number of fish kept in the same nest should not exceed the second generation, so as to avoid the species degradation caused by continuous inbreeding, which will make the fish body of the offspring smaller and smaller, and the dorsal fin shorter and narrower.
