There are a number of fish that Maf look at sideways now because they can survive and possibly breed in our natural environment (particularly in the North) Think of the discussions on this site about fish that should be tropical that are sold as cold water fish in the shops and the number of fish that can be kept outside unheated in the summer. In my view it would actually be quite difficult to prove all the things listed in the requirements by reef. This would particularly apply to livebearers, catfish and barbs amongst the many, and may yet be banned by Maf rather than added to. There is a member here who has recently submitted a PhD on some of the diseases carried by some reptiles in NZ. What do we know about these fish on your wish lists and who do we have that can make a convincing scientific arguement agains the "experts" at or available to Maf?
