One major concern with buying arowanas is that not all arowanas can be purchased legally. Currently, CITES has listed the Asian Arowana as an endangered species. While it is legal in some countries to buy and sell captive bred Asian arowanas, in other countries such as the US, it is not. Arowana breeding is common in many Asian countries. Breeding usually takes place in large fish breeding pools or breeding ponds as arowanas will not reproduce in an aquarium. Arowana breeding can be very difficult for some species, which leads to higher prices for certain arowanas. Other species of arowana are generally no problem to purchase, and cost less, yet can still be just as fulfilling pets and excellent aquarium fish.
As mentioned already, arowana fish are meat lovers. They are aggressive and you cannot trust them with other fish in the aquarium. They stay closer to the surface of the water and may jump out. A covered aquarium is recommended. If they are provided a healthy habitat, they may stay with you up to 20 years.
Arowana Tips :
- Substitution of water on a regular basis once every 2 days with a volume of 10% of the total volume of aquarium water,
- Total running water is carried out every 3 months. if you use pam water, should be allowed 24 hours in advance for the content of chlorine to settle, and after that can be inserted into the aquarium.
