Legal Arowana Species/Types in the United States
1. Silver (common)
2. Silver (Platinum) note: not a different species
3. Black (similar in looks wise but with black fins & other noted differences)
4. Blue "same as the above.
5. African (not really a Arowana)
6. B. Jardini (Australian Arowana or AKA: Pearl Arowana)
7. B. Leichardti "
Note: If you are interested in B. Jardini's & B. Leichardti's these are known to be the most aggressive type of Arowana. So if your looking for a Arowana to be kept together with other fish it is not a wise choice unless you're willing to take the risk...
All other Arowanas/ Asian Arowanas (Ex: Red, Chili Red, XB, RTG are all considered "Asian Arowanas" which are illegal)
