outdoor 150 gallon rubbermaid pond stocking ideas

Looking to set up my 150 gallon pond in the backyard and looking for some stocking ideas. Pond will be outdoors all year round in the sometimes harsh North East winters. I know Koi are pretty hardy to extreme cold climates but I believe they'll outgrow the 150 quick. Any other ideas?
