Hi Brad,
If you feed your shrimp, they shouldn't prey on your DSB too badly. Skunk Cleaners are the better of the cleaners, fire or scarlets can munch polyps. Nassarius are essential to your DSB and get a combination of Tiger Trochus and Certihs.. Maybe some nerites. The
coral banded, depending on the size of your tank, shouldn't be a problem if you feed well. They will eat worms and such, but one in a large tank won't do too much damage, not enough that your tank, once established, can't handle. I would add him last.
Scarlets are fine in small numbers.
It's always a good idea to seed your bed without predators for several months before adding them. Don't forget to feed your bed though.. a bit of flake should do it fine. Might also consider a cuke or two and maybe a fighting conch.
