I take one of those 8oz plastic deli containers and poke 20-30 holes in the sides with a hole punch. Then I place some Atlantic crushed coral in the bottom (~1/4" deep). Then I place some plastic netting (saved from bulk orange bags from the grocery store) on top of the ric to keep it upright. Finally, place some rubble surrounding the ric to keep the netting in place in the tank with full flow. The ric usually heals and attaches in about 1-3 weeks depending on how badly mutiliated the foot was in the fragging event.
