B and Q are selling some very reasonably priced pond water-lilies at the moment. We have just got one and it says on the packet that it is: "nymphaea marliacea albida". It also says *do not* put in the pond with Koi Fish. Now all our Koi died when we put in the pond some fish coming from China, which effectively exported from there a Koi fish disease some years ago. But we now have Goldfish,(some are pretty big). As i understand it goldfish are a type of Carp, as are Koi fish. So would anyone know if we can put goldfish safely in with this lily? Thanks.
