They are all pretty healthy! We did have a run in with a Heron in the spring that took some scales off the Black/orange Koi. But he healed up fast, can hardly tell where he got bit. I guess I must have done something right setting up my system. I never had a high reading on any of my water tests, even when I let too much time go between filter cleanings.
The black/orange Koi is named NEMO. Orange Koi is ZOE. I have grandsons who watch too much TV. Zoe 101 / Finding Nemo. They picked out those Koi.
Other fish are not named. I am sure the Catfish will eventually get a name. Probably let my DAD name him, he drools over my fish pond!!! Not because its a fish pond, he wants to FISH in my Pond!!!
Turtle is Jack, my 10 yr old grandson is the first person to see him in the pond, so got to name him.
