The Asian Arowana (Scleropages formosus), also known as the Asian Bonytongue, Dragon Fish, Golden Arowana, Red Arowana, or Green Arowana, is one of the most famous and highly valued freshwater fish in the world.

The Endangered Species Act is:
It is not limited to one individual state.
Therefore, ordinary hobbyists cannot simply travel to another state where Asian Arowanas are supposedly “legal” and legally purchase or import one through the normal pet trade.
The federal restrictions apply:
There is an important legal distinction.
It would be inaccurate to state:
U.S. Fish & Wildlife Service explains that possession itself is not necessarily an Endangered Species Act violation when a specimen was lawfully acquired and no otherwise-prohibited activity occurred.
However:
For an ordinary U.S. hobbyist, legally obtaining an Asian Arowana through:

Individual states may impose additional possession restrictions.

Qualifying captive-bred Asian Arowanas produced through registered operations may enter regulated international trade under specific CITES provisions.
Legitimate internationally traded captive-bred Asian Arowanas commonly have:
This helps verify their captive-bred origin and legal international trade status.
This distinction is extremely important:

Unauthorized activities involving this species may violate the Endangered Species Act and other wildlife laws.
Normal commercial importation and interstate retail sale to U.S. aquarium hobbyists are prohibited.
Federal permits or registrations for otherwise prohibited activities are restricted to qualifying purposes such as scientific research or enhancement of propagation or survival of the species.
U.S. Fish & Wildlife Service does not issue captive-bred wildlife registrations simply for keeping endangered wildlife as pets.
