It was the wagoi, but it's small. I am very hopeful it will resolve. As we know, these reticulated scaled ones are TOUGH.
Blue, my asagi which was a gift from Dick, is voted "The koi most likely to commit suicide at the show" each year. Not a mark on him, even though he lost one red scale from the underside somewhere.
Glad you are enjoying your ochiba Dick...they bring back fun memories of Ochiba Monday at Quality Koi.
The GR has not stopped eating since I put her back in the pond.
