New fish into the tank: When the new fish has just been bought back, the air pump in the aquarium must be operated for at least 24 hours to completely eradicate the chlorine in the water. If you have been using a biofilter, it is best to let the water reach a pH of 6-7 and the water temperature is 25 degrees Celsius. Add a small salt (approx. 1 or 2 teaspoons in each of 5 gallons or 20 liters of water) to the aquarium to reduce the risk of fungal attack and to make the fish healthy and increase its appetite. If conditions permit, it is better to be able to retrieve water from the original tank of your new fish and return it to your own tank (if the water in the original tank is not a problem), it is best to retrieve 1/3 so as to facilitate the new fish's adverse environmental changes. reaction. It is recommended that the arowana be raised from an early age.
Daily management: Change water at least 20%-30% per week, ammonia content should not exceed 0.1 parts per million (mg/1). Do not make abrupt changes in temperature or pH. If the change suddenly causes sudden death of Arowana. Test PH and other toxic substances every week to meet the bad policy. Be careful when changing the water, and avoid astrology. And when rearing arowana, you must avoid completely replacing it with new water, otherwise it will cause damage to the fish. If you see the fish's fins and scales falling off, it means that if you change the water too much and you can stop changing the water, they will naturally recover; but the amount of water to change is not too little, too little will make the fins opaque, Serious turbidity of the eyeball can cause the flap to flip.
Aquarium size: As Arowana is a large fish, the fish tank is at least 1.5 meters long, 0.5 meters wide and 0.7 meters high. The fish tank must be covered. Arowana is a fish that swims in the upper layer and likes to jump to avoid suffocation when no one jumps.
Light: Red Arowana needs a lot of light, and the best daylight is 4 hours. Other arowanas are also best able to reach 8 hours of light. Some fish lovers, such as redfish, like to use red light to treat red arowana, so as to achieve better results. The best light for Arowana is the daytime daylight. Long-term use of lights will obscure Arowana's back.
Filtering: Arowana larvae are too large to be raised in the tank. The problem of large-scale filtration of fish tanks is more prominent. The filtration systems that are suitable for Arowana farming include several types: upper filters, external filters, upper+pumped sand filters, and overflow filters. However, it should be noted that when arranging an aquarium, you should consider the advantages of arranging a water pump (surf pump). First, it can form strong water flow, second, increase the amount of dissolved oxygen in the water, and more. The important thing is that you can maintain a certain amount of exercise for Arowana to maintain the beautiful shape of the fish body. 4. It is also very important to avoid turning up the arowana and to use it for trimming during turning. Yang water motor can promote the development of smooth flaps.
Feeding of Arowana: When Arowana tries to eat too hard, it will hit a certain angle in the tank to cause injury. It is best to feed in the middle of the tank when feeding. Arowana is a meat-type animal, and most Arowana recipes are frogs, loach, cricket, goldfish, grasshoppers, shrimp, and so on. There is a problem of coloration in feeding, such as the red dragon, feeding red arrow or shrimp will play a role in the increase of red dragons, because the red arrow and shrimp body contains red pigment. The juvenile below 12 cm has just started to eat raw bait. At this time, you can feed freshly-sheltered white breadworms and shrimps (be sure to remove the head and tail; it is best to peel them into shrimp balls so as not to injure their stomachs. ), blood worms and other more palatable bait. Eat four meals a day for less meals. About 15 cm of small dragon fish can feed normal breadworms and shrimp (pumplings are best to remove the shrimp sword), but also can feed 1.5 cm fish. At this time, Arowana grows rapidly and its food intake is amazing. The number of feedings and the amount of feeding can be appropriately increased. Arowana more than 20 cm can be fed larger fish, shrimp, loach, meat and other bait. It is also possible to feed live baits such as various insects. These are foods that Arowana prefers, but care should be taken not to contaminate them. In addition, viscera, especially the liver is not suitable for feeding Arowana, and its more fat can cause Arowana disease. The goldfish in live baits are not a good food. Research shows that the infectious diseases or parasites infected by arowanas that feed on goldfish in narrow aquariums are almost entirely infected by goldfish. Artificial bait is best to use less fat beef, of course, if you have the conditions, you can buy finished Arowana special food. However, Arowana would not be accustomed to feeding artificial diets. It requires artificial bait breeding. If the arowana is 20 cm long, 15 fish and 15 square metre can be stocked in a 5 square metre aquarium. Tail, 40 square meters 40 tails, 200 square meters 120 tails. Visibility should be reduced as much as possible.
Arowana Feeding Technology
Arowana's survival requires weak acidic to neutral water quality, hardness requires soft water. PH value between 6.5-7.5, DH value of 3-12. Water temperature can be 24-28 degrees Celsius. The nitrite content and the chlorine content are preferably zero.
