2 goldfish in an outside pond.
I think we're on about v4 of the fish. Cats got some and the last pair didn't make it over the winter (I put a cattle trough heater in the pond to keep an air hole during Dec.-Feb.).
Come to think of it, we haven't named this pair. Before them was Flash and Dipstick, Jimi and Cleopatra, and Wally and Fiona. Alcohol is usually involved in the naming.
