If you add 8in feed trained LMB they may well become food for your 6 lb LMB. If you add large feed trained LMB you may well cause competition between the large LMB helping with the aggression question. I assure you that the LMB are eating you just can't catch them. The catchability matter has been discussed at length. If you want I can find those threads.
Bob stated at both the DFW and Atlanta meetings that as a general principal adding competition between LMB could have a beneficial effect on aggressiveness and improve catchability. It can also present a population imbalance problem in the pond. Here is a pic of feed trained LMB.

Jody these may be your fish.
