clean up crew help

Hey everyone, well just wanted to get advice on a clean up crew package on what and how many to get for my 55 gallon, 55lb rock. That i plan on adding in a few days



So far i have 2 peppermint shrimp, used to have 11 blue leg crabs and 10 snails but sold them to a friend, since i toke them out to see if my new rock was going to cycle which it didn't. But here is a list of things i see people most commonly added to a tank, my tank at least for the first year is just going to be fish only. So here it is, please add how much of each list.



Blue Leg Crabs: ?

Red Leg Crabs or scarlet red leg crabs?

Snails not sure what kind or how many?

Cleaner Shrimp ?



Thanks in Advice
