Best hermit crabs for detritus?

[Littorina]

Hey there!

Need to expand my CUC, and wondered if there were some hermit crabs that are more efficient than others for cleaning  up excess food and other detritus?  Read Scarlett's are very good, but they're a little pricey....

Thoughts?   Thanks  :-)

Nevermind!  I've been told by quite a few that scarlett's are the way to go   :-)

blue legs are the best for cleaning but most aggressive when they get bigger.
red tip are good cleaners and less aggressive.
scarlets are ok cleaners, not aggressive at all, looks good.
