Thanks for the advise on numbers and feeding. I will adjust as advised. It is sort of like overfeeding your dog or cat. When I go up to the tank they all coming swimming to the "feeding area" with these expectant little fishy faces looking out at me. But, I understand and will be strong from now on. Besides, chopping up worms twice a day is getting old, not to mention the looks I am getting from the wife. For some reason she has a problem with using the kitchen for a worm butchery. I would like to reduce the numbers so that I can add a couple of other species. I regularly catch pumpkinseeds, warmouth bream, and rock bass from the Elk river near the house. In fact a caught several last Saturday but they were too large to go in the tank with the size fish I have now. I will cull the current fish down to more reasonable numbers and let the remaining ones size up a little, then see about adding some more colorful native fish. I would love to add a small gar. There are plenty in the river but I have never seen any small enough for the tank. I will give periodic updates as things progress.
