I have kept those in one of my reefs. Definatly would recomend it. Two rules you need to follow though. VERY HIGH current, preferably with a wave maker (dont put it right on the output of a powerhead, unless you have a Tunzee Streams, because it can rip the tissue right off). Second, make sure to supliment feeding at least twice a week, either with phyto or zooplankton, or by stirring up the gravel with the filter turned off, and still strong current from the powerheads. That should prove a hardy species in a well lit, well fed, well circulated tank.
