Finally have pond going the way I want. Without re-digging and making it bigger, that is. About 4 ft wide and 6 ft long. tiered at 1ft and 2 ft. Second year with goldfish. Kept them over-wintered in house in fish tank. They started out as 2 dozen feeders and ended up about with 15 3-4" at end of last season. Bought another 2 dozen feeders this year. Put in a new 1000gph pump that runs the falls plus a frog spitter.
