Reef Clean Up crew

[daytonabob]

I need to increase the cleaning crew in my 58 gallon. My 5 snails 1 emerald crab, 1 Coral Banded and Horseshoe (I guess he's still in there) are on the over worked side. I am thinking of ordering one of the kits from Saltwater.com and was wondering if there are any NO NO's.. like who doesn't like who? Can I have 3 or 4 Shrimps, 2 or 3 crabs. without a fight breaking out?
Thanks!
