Ok - Sounds like I do not need to worry about larger RES, YP, or GSH eating small SMB next fall? I am holding off on adding crayfish (although some have already shown up on their own - probably out of the field tile) until I have some decent submerged plants so they do not hammer my water lilies. I think that I remember that it is hard to find a source for LCS. If the SMB will not be hurt by waiting until next fall, I am good with being patient.
