hi @nickhans!!!! thanks for taking the time....to leave such a deliberate comment my friend!!! your spot sounds amazing!!!!! as far as fish....i've found that simple gold fish work very well. they can take the temperature fluxes....better than most. these particular gold fish have been in this pond....for over ten years now. no filter..and no aeration...other than my hand scooping water out. the same colony of fish is STILL IN THERE LOL!!!! i don't feed the pond either. they eat algae..and insects.
