I think it's kind of a vast grey area the way it's written. All it indicates is "personal home aquarium" and that you can transfer said fish caught out of state (provided you obey all rules and regulations for collecting fish and the state you reside in). All the law really says is that you cannot sell the fish commercially (which requires a commercial fishing license, which have all been suspended).
Once the fish are no longer in Hawaii I seriously doubt Hawaii has any recourse - so it would be up to individual states if they choose to prosecute hobbyists selling a handful of fish. Unless the volumes and dollar values are there - I just don't see it even popping up on anyone's radar.
I have no problem with people legitimately travelling to Hawaii to stock their own tanks or replace fish that have died. And if they so happen to wind down their tank or sell off any of their fish (due to fish behavior, compatibility, etc.) - that's not really my call, either.
