Thank you, I saw that post earlier and will try to create a similar setup for the SMB. I have access to a bunch of rocks 6-12" diameter so will use those for the outside. BTW, what size will they spawn? My thought of getting smaller SMB this year was financial related, expecting them to be the 4-6" next year, which was recommended to stock next fall. I do realize they will eat some FHM until they get to next fall but there are a ton of FHM and figured 100 2-4" SMB wouldn't consume that many before next fall since all the fish being stocked are really small and FHM will continue reproducing until the fish get a little bigger (next fall hopefully).
