I can attest that LMB will swallow anything and I do mean anything they can fit in their mouths. I just recently released my LCS because the LMB kept eying them... He's grown so much this summer... From 3" to probably 8" plus. He is sucking down 4" goldfish like nothing now and ate two of my pumpkinseeds and 1 of my BG. HAHA He is so used to me putting feeder fish in, that he will take anything I put in and swallow it. So when I can't get around to buying or catching feeder fish, I he'll eat freeze dried crickets and krill. Every time I go to my dad's house, I'll catch a pile of grass shrimp. The bass and sunfish LOVE them! If you can believe it, I even catch some small blue crabs and the LMB eats them as well. You should see him taking on a snapping 1.5" blue crab!
I'll see if I can take some recent photos to post...
Here are a couple older ones:
