Got two small ponds in the frount yard with a few specks. Don't catch them .They are really after a while become pets. Got a wee mink who nails the odd one. But that is what he is supposed to do. The worst offender is the herron who nails everything frogs, fish and leaves the large ones he cannot swallow to die on the bank. There should be a season on those critters.Ponds are ok but a lot of work. Steve
