My daughter and I went down to the pond this evening to try the fishing. The sun was just setting and the full moon was about to rise. All we had for tackle was an old simple cast reel and a hook that should be too big. All we had for bait was a hot dog from the grill. In just a few casts we each had caught a fish. I do not know what kind of fish they were. Hers was about 9″ long, My fish was a couple inches shorter.

I found a web site that lists Texas freshwater fish. It looks like a small Large Mouth Bass or a Green Sunfish, but I am not sure.
