I bought the hobby pack to restock my pond this past Spring and I couldn't be more pleased with the mix I received. I have this wonderful extremely colorful variety of both standard and butterfly koi. A great mix of colors and as promised, I have some truly sensational fish. It has been so fun watching them grow. The fish are healthy and the initial loss was less that the 20% I was expecting. I unexpectedly received a couple of absolutely stunning Sapphire Koi, they are exceptional! I have always purchased my fish individually, but this has been such a fun experience I am now sold on peanuts.
