Elite Detail,
That may be a difficult undertaking considering that you will need to keep the water cooler than room temperature. You may need a water chiller, especially during warmer months. Dr. Bill, if he is reading, may know better the temp. limits that fish from our area can withstand. In college, I foolishly attempted to keep small rainbow trout that I had caught in a 100 gal. aquarium. I didn't have a chiller and was constantly putting ice in the water to keep it the same temp. as the water in which I caught them. Though it was somewhat of a neat experiment, I realized that they wouldn't survive that long, so after about a month I released them. They were still too small to eat. I too think an indigenous species tank would be interesting to keep, but for now will keep my reef tank.
