Points to keep in mind when mixing swimmers
First of all, Asian arowanas have a docile disposition. However, if you mix them with aggressive species, there is a high possibility that they will fight. Therefore, we recommend that you mix the Asian Arowana with a low-swimming species such as the Pleco.Asian arowanas are carnivores and often recognize smaller individuals than Asian arowanas as food and eat them if they are mixed with them, so be careful about the size of the species you are mixing.

Points to keep in mind when keeping Asian arowanas
The Asian arowana is one of the most popular varieties of ancient fish because of its long, slender body shape and leisurely swimming appearance. In addition, some species are often sold at high prices due to their body color and rarity. Since they are traded at a high price among tropical fish, there are even specialty stores specializing in arowanas. One thing to keep in mind when keeping Asian arowanas is the speed of growth. Because the Asian arowana grows very fast, it is recommended that the aquarium in which it is kept be at least 120 cm in length.This is because even if you purchase a small Asian arowana, once you start keeping it, it will quickly grow and a small aquarium may become too small for it. If you keep feeding them the same food for a month or so, they will get bored with it. Even small-sized Asian Arowanas are sometimes sold at surprisingly low prices, so those who are considering keeping them should be prepared before purchasing them. The Asian Arowana has a beautiful, showy body color and a massive physique. If you are interested in Asian Arowanas, we recommend that you take a look at them at a specialty store.
