CATDOLL : CATDOLL: What should I feed my arowana?

1. What should I feed my arowana?

Young dragon fish under 12cm begin to eat raw bait. At this time, you can feed them white mealworms that have just shed their shells, creek shrimps (just shed their shells) with the head and tail removed, and bloodworms. Pay special attention to feeding during this period, and eat small and frequent meals, which is particularly important for the growth of young dragon fish.

Arowana breeding environment

1. Water quality: Arowanas need weakly acidic soft water. Generally, tap water from rivers is weakly acidic, which is suitable for arowanas. However, tap water contains chlorine or fluorine, which is harmful to arowanas and may even cause death. Therefore, when raising arowanas, the water must be stored for 1 to 2 days or exposed to sunlight for half a day to allow the chlorine or fluorine dissolved in the water to disappear on its own. If a very small amount of baking soda is added to the water, the chlorine can be decomposed. If tap water, well water, or mineral water from underground is used, the hardness may be high. One-third or one-half of boiled water or distilled water should be added to reduce the hardness of the water. Old water in the aquarium for a long time will generally become hard water due to evaporation, and should be softened in time. The simplest way to soften water is to boil the water first to remove impurities, or filter it with an ion exchange resin filter.

2. Water temperature: It is best to keep the water temperature at 24℃～26℃, especially for silver and black dragons, the water temperature needs to be raised to 28℃～30℃. Dragon fish are very sensitive to sudden increase or decrease in water temperature, which can easily cause nervous system shock, absorption interruption, and lead to death. When raising dragon fish, the water temperature must be strictly controlled. Especially for dragon fish raised in an aquarium, the temperature difference between the new and old water should not exceed 2℃ when changing water, and when the new water is injected, it must be poured and spread. When the dragon fish is transported to a new environment for breeding, it should be waited for about 15 minutes until the water temperature of the transport container is close to that of the new breeding environment before putting the fish in.

3. Oxygen and light There are two main sources of dissolved oxygen in water. One is the product of photosynthesis of aquatic plants; the other is directly dissolved from the air. However, the decomposition of leftover bait, fish excrement and dead branches and leaves of aquatic plants in the water also continuously consumes the dissolved oxygen in the water. Therefore, various dirt in the breeding pool and aquarium should be cleaned up in time. In order to ensure that there is enough dissolved oxygen in the pool or aquarium, oxygenation equipment should also be equipped.

Raising dragon fish can also plant water plants

In addition, the consumption of dissolved oxygen in the water is closely related to the stocking density of arowana. According to the author's experience, the optimal density for arowana breeding is calculated based on a fish length of 20 cm and a water depth of 50 cm. 15 arowana can be raised in 5 square meters of water surface, and 30 arowana can be raised in 15 square meters. As the water surface expands, the stocking density can be appropriately increased.

Fish need moderate light during their growth. It is best if the sunlight can shine into the water for 3 to 4 hours twice a day, morning and evening. If the light is too dark, the dragon fish will move stiffly, have a poor appetite, and have a dull color. If the light is too strong, the dragon fish will also swim abnormally and even develop bubble disease.

A filter is definitely needed, and a surf pump is not necessary, but a heating rod and a light tube are also needed. You can ask at the fish store about these.

3. How to feed arowana?

It is best not to feed the 10cm-long dragon fish directly, because there may be many pathogens in the live fish, which can easily make the dragon fish sick. It is better to feed it with feed. Generally, it is best to buy the whole shrimp feed in barrels at the fish market. This feed can make the fish grow faster and is conducive to the coloring of the fish body. Secondly, you can choose to buy a feed called "brine shrimp", which is also sold in general fish markets. It is a frozen food that can be fed directly after being dissolved in water. This feed is nutritious, conducive to growth and coloring, and fish love it very much, but the price will be a little more expensive.
