Hey Bill, thanks to you and everyone else for the great thoughts. Honestly, my interest is just because it would be cool to see what's going on down there....especially at the microscopic level. For one thing, I'd like to know what my little FHM are feeding on? I'll probably wait a while, then probably get the microscope and the net at some point and see what's what. I'm planning to stock a big batch of FHM and GSH in March, then SBS and HSB in the fall. Maybe some Tilapia as well, but we'll see how things look then.
