Yes, Asian Arowana will probably be legal soon, when the act is repealed, but will probably be back in some form I the not to distant future. The Asian Ariana should not be listed, if it is already covered by CITES the USA really doesn't need to deal with a foreign species in general. But if the act goes, I am more concerned about many endangered native fish, that will lose protection, I hope that some killifish keepers are given some of the endangered pupfish to breed. As for Arowana we will most likely have to import them from Canada. Maybe someone can start a farm in Florida.
I would bet they will be legal to have within 24 months, but the ESA will be replaced at some point, maybe not under this Administration, but in the not to distant future, and we may end up with even stricter laws and a not well thought out bit of legislation. The ESA is pretty well drafted, and I would hope it is just put back up as is, minus Asian Arowana, I mean Tigers are on CITES Appendix 1 and there are more tigers in Americans yards than their are in the Wild. Tigers are no where near as mass produced as Asian Arowanas. The point is that Asian Arowana should not be under the ESA in the first place. We should lobby to get it delisted, not that hard probably, a couple well presented facts should do it. The point of all conservation is to delist something, or it should be.
Leaving CITES though is much more dangerous, if we left the whole thing might fall apart, hopefully it doesn't but their is no guarantee.
