Conner, in all honesty, I don't think you will be able to stock enough minnows to make a difference. If you stock FHM, the GSF will eat them. It's better to stock the LMB and let them chow down on the GSF. LMB do very well on eating BG without minnows, and will do the same on the GSF.

If anything, you'd have to stock adult GSH, and the LMB will like eating them better than the GSF, so you'd be defeating the purpose of adding the LMB. (You wanted to reduce the GSF population, right?)
