Peppermint shrimp VS Cleaner Shrimp

[ch0ch]

I have 2 peps in my tank... and just found out that they eat feather dusters... ( they actually ate them in front of my face after observing for 5 mins) so i am unhappy... So I would just like to know the pros and cons of both of these species because I dont want to purchase a cleaner shrimp and then find out that I was better off with a pep. shrimp.

 

Pros would be something like eats parasite (Example)

Cons would be something like eats dusters/sea stars and what not.

 

thanx for your help

and if anyone has suggestions other then these two by all means do not be shy.... cuz i am really ???
