The remaining SMB in my RAS system still prefer hydrated sinking pellets to floating pellets but I haven't forced the issue yet, it's coming though. I am waiting on a fresh bag of AM500 to come in, hopefully next week. I do have a handfull of SMB (biggest ones in the tank) that have no problem eating non-hydrated pellets off the surface.
Shorty,
I would bet once they got hungry enough they would all feed on the dry pellets especially with some of them already doing so.
Perhaps initially not pinch the hydrated pellets to allow them to stay a float and then go to dry pellets?
