hey guys, I've been away so just catching up on threads now.
No, there's absolutely no way freshwater stingrays would EVER be allowed into the hobby in NZ. No matter how much money you threw at it, they would NEVER be put on the allowable import list.
Yes, zoos and public aquariums would potentially be able to get permits to import them but they would definitely not be allowed to sell any to private persons.
Yes, freshwater stingrays have stings, and yes they can kill (depending on species).
And finally, NZ has native marine stingrays, eagle rays and electric rays, all of which would be legal to keep -- so long as you have an enormous tank!
