Brett, I bought my LMB from a fish farm nearby. They had the bass in a big tank made from a grain bin ring with a liner. I'd guess that they were feeding them pellets. I started feeding high protein trout pellets the first two years then switched to GFC the next two. I would occasionally see LMB taking pellets but they seem to like the Aquamax largemouth much better as do the channel cats and hybrid stripers.
Below isn't a great representation since it was two different times of year and photo's aren't great but there is definitely a lot more meat on them now.
