Crayfish would be neat and won't leave.

I just started a small pond recently. I currently have a few small
goldfish
in there. I would like to add some other unique creatures. I would
rather
not build a wall around it, which I am told is necessary for turtles and
frogs. I have looked at mystery snails. What else would be good to add?

Thanks, Scott
