Hi MattWI, I am curious about this same thing. I have a recent post that I mentioned about calling my fish supplier. He said that they open up a RBT once in a while to see what it has been eating. He claims that once in awhile their stomachs will be filled with BG fry up to an 1.25" long. He suplies RBT in the 10- 14" range, so I imagine he is talking that size, or bigger. I would also think that the RBT would go for a prefered food, but I don't really have a clue about this. I hope for more answers myself.....Jim
