Reef Tank Cycle

After my SW tank cycles what cuc’s should i get?
i have a 14 gallon nano Reef Tank with about 14lbs of live rock and 20lbs of live sand. Crabs are usally first, which ones and how many? and as for snails i think i need around 6-7 maybe 2 nassarus and which other are good?
i hope to add a few coral in the future so they need to be coral friendly
for crabs I have read that you should stay away from the emerald crab. Might not be reef friendly. Get some hermit crabs. Nassarus snails are suppose to be good for cleaning the sand. My LFS doesnt have any right now so I have been waiting to get some of those myself! Right now I have 5 astrea snails and 10 hermit crabs. I recently added 3 red astreas. Not having good luck with those. One of my hermits already killed two looking to steal a new shell. Oh, for hermits make sure you put extra empty shells in there! If not they will kill and rob snails of their shell. I have heard to stay away from turbo snails in a nano. They get kinda big and might knock your corals over. Good luck!!
