I'm not so sure the bass is a spotted. They normally have a very pronounced tricolored tail- black at the base, white at the edge, and red or orange in between. They also usually have a lot of dark spots below the lateral stripe. If I had to guess I'd call it a Florida bass. I had a nearly identical bass that I got from a feeder shrimp tank and was trying to grow out to get a better ID on, but he died on me.
Your feeders by the way are a mix of mosquitofish (Gambusia holbrooki) and banded killifish (Fundulus diaphanus), a more northern species which has been introduced in the Augusta area.
