Fish are sometimes known as Irian Arowana is living in conditions fairly wide range of pH 6 to 7.5 and at the temperature of 22-270C. It is also advisable to take care of the low hardness water areas. pH is an important factor to consider, it is because if the pH exceeds 7.5 will cause problems for the fish eye. Jardinii Arowana fish is very sensitive to water conditions, especially the content of ammonia and nitrate should be kept to zero. Filtration system must be effective to keep the water clean and about 15-25% water change every week. Another reason to keep the water conditions are prefect for fish prone to fin rot problem. The minimum tank size is recommended for the treatment of 180cm x 60cm x 60cm with a capacity of 680 liters of water. These fish need a space large enough pool decoration tank is not an important thing. The top cover of the tank needs to be given the reputation of the fish which is considered a reliable jumper.Arowana jardinii has a worse temper than silver arowana and very easily startled (stress).
This fish is also more aggressive so it is not recommended for beginners. Some sources say these fish are territorial so it is not advisable to combine it with other types of arowana in one tank. But
that does not mean there is not a suitable tankmate, such as pleco
fish, oscar, catfish, silver dollars, red belly pacu, knifefish,
datnoid, cichlid fish is an example that can be tankmate. It is important to choose tankmate is the difference in body size of fish that must be balanced. Fish
are much more aggressive and highly territorial nature is not
recommended for tankmate arowana fish like other kinds and types
managuense. The
number of fish in a fish also affect the comfort of the fish due to
lack of movement area, if the tank is large enough, the number of fish
tail 6-10 not considered sufficient to cause fights. However, to further maintain the convenience of fish, if the fish is better cared for in an individual.

Wide mouth with large cavities used for egg Incubation. Another difference is the size of the male's head is relatively bigger, more aggressive nature, Including in the struggle for food. Few fish farmers have successfully grown. Techniques spawning (breeding) is very difficult when done in the aquarium, and the likelihood of success if done in a pool. Just as species from Asia, Arowana jardinii mouthbrooder species but the difference is the female parent will not keep the fish during the process of incubating chicks. Puppies fish only once at the mouth of the female parent, they will leave in search of food. If danger approaches, the mother will give the signal for them to return.
