I am putting in galvanized cyclone fence in the new pond to defeat the rats. Need to trap them in the old pond.
There are some surface insects on the water now. Also there is a lot of grass I planted on the embankement to minimize erosion, some now under water along with some decidous leaves. Along with the tree trunks I think the basic ingredients for insect growth are present. Crossing my fingers and going to order the fish soon.
