Hello! I am thinking of getting guppy’s for my 600liter outdoor pond I am in Taranaki and hope it’s warm enough for them I am just wondering there are a lot of wild gambusia in my local river and I know they are pest fish and it’s illegal to sell them. I’m just woundering if I can breed fancy or normal or maybe even endler guppy’s with them and Make them more hardy in the cold water and sell them for profit or just try some things with them or is this illegal? Thanks very much!
