You can just buy whatever you like at the LFS or you can check saltwaterfish.com or other various online retailers for a cleanup crew. Just make sure you get a good share of hermit crabs, snails, and maybe a few emerald crabs. I would NOT put in meds as I think that is strictly a last resort. I would always try the natural way first.
