As mentioned previously, including fish arowana not difficult to maintain. What is needed is to spend some time every day or several hours each week to care for them and check their condition (See Routine Maintenance Tip Aquariums). Here are a few things to consider in keeping arowana.
In general, the larger the size of the aquarium would be better. For large fish arowana require considerable space. The length of the aquarium is recommended 3 times the length of the fish that are maintained, while its width is less than 1. 5 times the length of the fish. The aquarium should be placed in a place that not too many activities / disturbance, to avoid fish stress widened. Also avoid sudden ignition of the lamp, this often causes the fish to panic, sehigga fish can hit the glass or other objects in the aquarium and the fish could be injured. Aquarium with a good lid to avoid jumping out of an aquarium fish. Make sure there are no holes that could be breached by the fish on the lid akurium berasangkutan and also make sure the lid will not be driven by the strength of the fish jump.
Manipulation of lighting can often lead to the reflection color of the fish better. Place the lamp on the front of the aquarium, and set the corner reflector in such a way that it can provide an optimal reflection. Many options lamps sold in the market with varied spectrum, you can bereksprieman spectrum and choose what you want. Full-spectrum lamps will naturally reflect the natural colors of the relevant advertisement.
pH. Arowana can live on a fairly wide pH interval, however, adapted to its original condition, in nature, it is recommended that they be maintained at intervals neutral to slightly acidic pH (pH 6.0 - 7.0).
Hardness. Arowana originated from waters with low hardness, therefore, recommended to maintain it at an interval of this hardness (GH = 8 °).
Temperature. Arowana is recommended to maintained at a temperature interval 26-30 ° C. As with other types of fish, avoid sudden temperature changes. Sudden temperature changes can cause shock to the fish in question, and can lead to various problems. Temperature is too high for a long time been known to cause gill cover roll up, this would be very menggangggu beauty of the fish.
Replacement of Water. As carnivores, Arowana will produce manure in relatively high amounts with high nitrogen content of the element. Therefore, the levels of ammonia, nitrite, and nitrate in the aquarium arowana is often a problem. Unless you have a good filter system, then the replacement of water on a regular basis is the thing to do. Replacement of water by 25-30% per week is recommended. If you have a lot of time can also be replacing every two times a week as much as 20%. The replacement of water, should be noted that the temperature and pH of replacement water must be relatively similar to the aquarium water. Avoid the occurrence of spike parameters of water at the time of replacement water.
Giving Feed. Feeding the Arowana can be done in various ways. In general it can be said for arowana with body length of 35 cm above the feed can be given once daily or every other day. (Remember that in nature they may not be able to get food every day. Diet to follow this natural pattern can often prevent health problems in the arowana). On Arowana with a length of 15-35 cm in the feed can be given 2 times a day, while for arowana with a length of less than 15 cm, it is recommended to be given food three times a day.
Type of feed. Arowana is a carnivorous fish, in the wild they eat insects, fish, shrimp, worms, and some types of small amphibians like frogs. Therefore, the live feed is the main diet for the arowana. In many cases arowana can also accept artificial feed, tertuma after going through the stages of introduction first. As recommended for other fish species, feed should be given to vary. This method will be able to reduce the risk of specific nutritional deficiencies in fish is concerned. With the varied nutritional needs that can not be met by one type of feed, is expected to be met from other types of feed. Take your passion with a desire to brighten the color of the fish. Color is a gift of mother nature, which have certain functions and duties on fish, and animals in general (described elsewhere). Identify the function of color on the fish (and animals in general) before you fill your pet with food-specific artificial feed. If your fish healthy and given a balanced diet and a pleasant environment for the fish so they will show gratitude to reveal brilliant color.
Avoid the type of feed containing high levels of fat. High fat content is known to trigger symptoms of eye drooping (eye drop). Nor should you give food to excess. If the Arowana have long-term excess feed, they will lose their appetite and will not want to eat for several days or even weeks. Excess feed is not a rare cause of short-lived Arowana and to some extent will affect her reproductive ability.
The use of live food should be preceded by adequate quarantine measures. This needs to be done to avoid the entry of germs into your aquarium system. Especially, from the types of live food originating or living in water, such as shrimp, fish, or frog. Also avoid giving the insects that have died, because of the possibility that insects die from the insecticide, unless you are absolutely sure of its origin. Once the bulla with toads, frogs often harvested from polluted waters insektsida.
In providing the live feed, discard the parts that may injure the fish's mouth, such as jumping leg (back leg) on cockroaches or crickets, or thorn "horns" at the head of the shrimp. You may also weaken the live feed before feeding on fish, to avoid "chase" redundant in a narrow space aquarium. But do the attenuation was by way of "animal".
Several types of feed are often given at the arowana is:
Fish. Live fish, fish meat
Shrimp. Live shrimp, shrimp meat, krill.
Insects: Crickets, Cockroaches, centipedes
Worm / worm: silk worms, earthworms, bloodworm, Hongkong caterpillar, caterpillar bamboo
Amphibians: Frogs, lizards
Artificial Feed: Pellet
