How big does a pond need to be for sticklebacks?
I've just finished putting in a pond which I'm hoping will attract lots of wildlife to the garden. I'm now thinking of making another smaller one so that I can have some sticklebacks. I'm aiming to keep the first pond stickleback free as I thought they would eat lots of the things I'm trying to attract! How big does a pond need to be for sticklebacks? We're on the east coast of Scotland so I need to go big enough so it doesn't freeze solid in the winter but just wondered if anyone had any thoughts on minimum size? Thanks!
