Larger fish eat all of the above. Some of the larger bugs and beetles will actually eat the smaller fish. As your fish grow a little, they will be out of danger, and eat the bugs and beetle larvae.

My stocking year was the same as yours. I had millions of back swimmers, assorted beetles and bugs. Now that my fish are larger, I seldom see any, and when I do see one he better be running for his life.
