Hello I was thinking of making a pond but want to make something g that involves less digging through rocks&roots. So I was wondering about a big fishtank that I could build outside with a big viewing glass window in the frond and maybe in the side. And what kind of fish I could put in other than carp or goldfish that can survive a new England winter. I'm thinking bass pikes and other native fishes but would love some other ideas of big exotic fishes. Any info will be helpful
