Oh goodie because I do love to see them all. And this one baffled me for a while. We lost all of the fish in the front bigger pond once before my Mom passed away(hubby and I cared for her for two years). Not sure what got them but they got all of them overnight, all we found was one cleaned set of bones. So after that we got some more koi, Goldie's, and the other ones that are in their, think they are shabunkin. Last year was the first year we had babies, and our original 12 have grown to about 25 now. I am going to have to probably get some moved to the little ponds and rehome a few soon, I really need to figure out how many we can safely have in there.
