Last weekend, the water in both of my ponds was so crystal clear. Not sure if it was because it got cooler, or just because I was looking at the right time with the sun shining at the right angle, as ponds have been very clear all summer. Koi still think they need to be fed, but only feeding them cool water food, and only every other day. I just have to not go look at them on the off days. LOL
Shamu still thinks my job is to toss food directly into his mouth. He is the only one that does this open mouth thing, begging for food. He's the one with his mouth wide open in the previous pic, too.
The others come to the surface but don't open their mouths.
This is Lucy, the red-head. I actually got her from the local pet shop and she is probably my matriarch, although she was not the largest when I got her. Shamu was the largest fish the first year, but she has outgrown him, or maybe it's just that she is a fantail, and he is regular fin.
This pic the koi were all at the bottom of the pond, where it is nearly 4' deep, to give you some idea of the clarity of the water.
