You might find occassionally throwing a little feed to whatever lives there to be quite relaxing as well.
Even if I only had a tiny little water garden pond, I'd go find some GAMs to keep the mosquito hatches down. A very beneficial minnow, indeed.
Oh, I loved feeding the fish. I did it nearly every single day, spring through fall. 2 of the original LMB I stocked in would follow me around the bank.
A lot of the fish disappeared last year. I think there was a ph crash after an enormous amount of cedar needles got washed into the pond. Made a bad mess of it, not sure what else it could have been. Since the pond needed to be drained for repairs/modifications, we went ahead and removed the rest. Less than a 5-gal bucketful of LMB went to a neighboring farmer's pond.
ETA: So far as mosquitos are concerned, the aerator is big enough to keep the entire surface of the pond rippling 24/7. I assume that (and numerous frogs) keeps mosquitos disinterested in turning it into a nursery. But I do really like the idea of gams as a backup.
