How to raise red sword and anchovies

Raising of Red Swordfish:

1. Prepare a fish tank, the size will be determined according to the number of Red Swordfish. Try to make it as big as possible to allow the fish to have more space for activities. When fishing for swordfish, it is best to control the water temperature around 25 degrees to 28 degrees.

2. When there is a lack of oxygen, red swordfish will concentrate their activities near the water surface. 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 The water suction pipe sucks away the dirt 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 there is oxygen in the water. Water is absorbed or added. Try not to touch the fish when doing so to avoid damaging the fish's fins. ,

3. To distinguish between male and female red swordfish, the distinction between male and female red swordfish is based on the tail: the one with a sword on the tail is male, and the one with round tail is female. The tail of the small fish is round, and as it grows, the male fish will grow a sword.

4. The tail of the red sword is beautiful, but they also like to chase and bite, and often bite their own tails. Therefore, it is best to keep red swords instead of other aggressive fish, such as tigers. Skin.

5. You can feed red swordfish with professional fish food, and bread crumbs can also be used. Red swordfish is not very picky about food.

6. The female red swordfish gives birth once every 4-6 weeks. The size and age of the female fish are determined, and the proportion of breeding male fish is affected. Each time, 30-300 larvae can be produced. When breeding, attention should be paid to not leaving more than two generations of brood fish in the same nest, so as to avoid continuous inbreeding leading to breed degradation, resulting in smaller and smaller fish bodies and shorter and narrower dorsal fins in the offspring.

Raising of anchovies:

1. Water temperature: The water temperature should generally be controlled between 18 degrees Celsius and 34 degrees Celsius. If the temperature is lower than 18°C, anchovies will suffer from loss of appetite, listlessness, etc. It is also very susceptible to diseases such as saprolegnia. As a Feng Shui fish, it's usually fine. But as a food fish, it needs to be cultured according to the situation.

2. PH value: The most suitable PH value for anchovies is generally between PH6.5-PH7.5. This PH value has a great impact on anchovies. Maybe if the pH is a little higher or a little lower, the anchovies will die.

3. Hardness: The requirements for hardness of anchovies are generally around 10-15 degrees. Although experts say this, there are completely different examples in real life. Just like Germany and Japan, the water quality in the two places is hard water and soft water. Anchovies can live in both places.

4. Nitrite concentration: Nitrite concentration also has an impact on anchovies. If the concentration is too high, it will still be harmful to anchovies.

5. Feed: Regarding the issue of anchovy feed, it is divided into three types: flake feed, pellet feed, and frozen feed. Of course, there are also feeds specially developed for them.
