How to raise arowana?
1. Water demand
Overall, arowana is still relatively easy to raise. Arowana likes weakly acidic to moderately acidic water, with a pH of 6.5-7, a hardness of 3- 12 dH and a suitable water temperature of 26-30℃. It is necessary to change water regularly. If the water is not changed for a long time, the fish's fins will be opaque, the eyes will be turbid, and the gill cover will turn over easily. However, if the water is changed too frequently, the rotten fins and scales will fall off. Generally, the initial exchange water volume is about 1/7, followed by 1/4- 1/5. The water change temperature should be within 2℃ of the bath water temperature. The fish tank is three times as long as the fish. Submersible pump should be 20 cm below the water surface. Don't put decorations, so as not to hurt the fish. The water tank needs to be covered to prevent fish from jumping out.
2. Feeding requirements
Arowana is a carnivore, and likes eat small fish, goldfish, loach, shrimp, snail, breadworm, cricket, cockroach, shrimp, fish, pork and beef. You can also eat synthetic feed after taming. It is not advisable to feed dead fish and shrimp. Soak in potassium permanganate solution for half an hour to about an hour before feeding, then clean it before feeding. Shrimp and the like need pruning, and the remaining arowana must be fished out in time to avoid damaging the water quality.
3. Feeding arowana at different growth stages
1.2 cm young fish can be fed with newly hatched bread worms, newly shelled decapitated shrimps and blood worms, with three meals a day and few meals.
1.2 ~ 25 cm young fish are fed with bread worms, small crickets, 1~2 cm small fish, 1~2 cm small cockroaches, decapitated shrimps, etc. Need to feed floating ingredients to prevent eye drops. Three meals a day, each time 10 minutes.
25~45 cm sub-adult fish, this is the coat color stage of arowana, so it is not necessary to feed more to avoid obesity. Feed it once a day, and use shrimp, crickets, cockroaches and other foods containing astaxanthin and carotene to promote the coat color of arowana.
At the adult stage above 45cm, the growth tends to be slow, and excessive feeding will cause fat accumulation, and only 1 time can be fed a day, mainly artificial feed and small fish, shrimp, breadworm, SINONOVACULA, fish and shrimp meat.
Second, what is the best for arowana to eat?
First of all, arowana is a carnivorous fish. When feeding, it is best to feed some small fish and shrimp. Small fish can balance nutrition, and the red pigment in shrimp will help the hair color of arowana. Wheat worms, loach and insects can be fed, but don't feed more, because the fat content of wheat worms is too high, and long-term consumption will also make arowana fall out of sight, while feeding more insect bait will make arowana picky eaters, so it is recommended to feed less. Feeding centipede can increase the brightness of arowana scales.
Three, the four stages of arowana hair color
The first stage: gill cover is red.
The gill cover of arowana began to change color. When arowana grows to about 25 cm, the gill cover will begin to appear diffuse color. The larger the color range, the better, but its color quality. Generally, orange or pink is better, and the thicker the color, the better.
Stage 2: The first scale box is red.
When the arowana grows to about 30 cm, the first scale shelf in the first half of the body begins to change color (it should be noted that at this stage, the coat color of the arowana gill cover will continue until the best condition).
Stage 3: The second scale box is red.
Generally, there is a feeling that the hair color of the first scale box stops after a while, but in fact, the hair color is not obvious. When arowana grows to 30-40 cm, that is, about one year, the second scale frame begins to develop color, the first scale frame becomes thicker, and the red area of gill cover increases. This stage is the most important stage, so we should pay more attention to diet and lighting.
Stage 4: Redness persists.
At this stage, the coat color of arowana is basically thicker, the discrimination between scales and frames is reduced, and the red range is increased. At this time, arowana is about 50 cm. The hair color of arowana is a long and tortuous process. Sometimes the hair color will suddenly stop or even fade, and sometimes it will be surprisingly good. These are all normal phenomena. If you want to finally get a bright red arowana, you must be patient, because the color of arowana will never stop, and it will take about 5-8 years to complete. Wouldn't it be a pity to give up halfway?
Fourth, the longevity of arowana.
Generally speaking, the life span of fish is related to its individual size and sexual maturity age. The bigger the fish, the later its sexual maturity and the longer its life span. The life span of fish varies greatly among species, but most fish live between 2 and 20 years, and 60% of them live between 5 and 20 years. The fish that can live more than 30 years will not exceed 10%, and only 5% will live less than 2 years. Because arowana is a big fish in tropical fish and has a long life. Jinlong and Honglong have a long life span of 40 years; Silver dragons are very short, and generally only live for 20 years.
According to the living habits of arowana, the body length of adult arowana can reach 80~90 cm. The service life can reach 40-50 years. In general, it is no problem to raise 10~20 years as long as the feeding conditions and methods are acceptable.
5. The price of arowana
The price of arowana varies greatly, which first depends on the variety of arowana. Arowana has orange. Pink, crimson, blood red, etc. The redder the color, the more expensive it is, among which blood red is the most significant. Secondly, whether arowana's back shines more than its back. Generally speaking, those with bright backs are about two or three thousand yuan higher than those without bright backs. Thirdly, there is another problem that affects the price of arowana, that is, the cost. Arowana is dominated by loach and grass carp, which has high feed cost and high water quality requirements, resulting in high water and electricity costs in fish tanks. These are all factors that affect the price of arowana.
