It's been a while since i've update this little thread...soo...new pic of the pond, first off:
Pond doesn't look great, but for a small little ecosystem it's doing very well. fish are fat, colorful, no disease.
Since the last update, i've added two new fish, a calico ryukin and a gray oranda. the oranda died of bloating, unfortunately. today i discovered 1 small single-tailed baby goldfish too, i haven't seen any more babies. So now there is 7 fish in the pond. Still wanting to add 1 or 2 more, maybe another ryukin, since they've proven to me to be as hardy as the commets/commons.
