ive just brought a house which had a measly 6 inch deepx 3 ft round pond with a couple of goldies in it... i thought this was cruel so i tryed extending it, ive now made it 12 inches deep and 8ft wide BUT i was told goldfish will not survive in a pond only A foot deep is this correct as ive now finished the pond and do not wish to dig it back up......do we really have that bad a winter for it to freeze solid in the uuk
