Best (as said above by David P) is to find a local SPS'er in your area and buy one off of them. A great alternative is to talk to a vet and honestly explain what you will use it for. Third, you can just live with RB's. They don't kill SPS.. it's a common myth that they suck up the slime but it's all anecdotal experience. I know plenty of SPS'ers who have RB's and at the same time have beautiful thriving colonies. RB's are NOT destructive like Monti Eating
Nudis and
AEFW's.
