The first thing you have to do is contact Cites with a list of the fish you want to import. So long as they are not endangered you will have crossed that hurdle. Then you may or may not have to contact dept of fisheries. If you are importing fish that can survive in cold water there may be restrictions there as well. Then you are going to have to arrange shipping.. very expensive. I assume this is for personal use, if its for business there are more requirements as well. Factor all of this into your costs and see how cheap it really is...Worth it?? Maybe yes , maybe no..Hope it works for you..Keep us posted
