The mandarin was one of the main motivations for my 90g tank. The issue really comes down to size. No matter what you do, the RSM cannot support enough of a pod population to be self sustaining in the presence of a mandarin. Since most will only eat live pods that means you are either spending $25-$50/mo on supplemental live pods and running a breed out tank, or your mandarin will starve. I have been running for almost a year now in my RSM, I tried adding a HOB fuge, and a sump in addition. While I do have an excellent pod population, it is not enough in the RSM. With an established 75g tank or larger properly stocked with Live Rock and a fuge, this shouldnt be a problem, in fact the mandarin could almost be an afterthought. Pods are pretty good breeders, and as long as they have enough space to create a sufficiently large population, they will take care of themselves.
