Peppermint shrimp, need a couple

[Drfu]

I have a small outbreak in both of my tanks of Aiptasia anemone, do you know which lfs in Calgary sells the real ones, not Camelbacks? I have read that only the true peppermint will eat them!

Also how compatible are they with the following:
Sexy Anemone shrimp?.......they are quite small and might not like having another shrimp in their home (tank is 8 gallons and has two sexy's & two small o clowns).
Skittish Hi Fin Goby/pistol shrimp pair (15 gallon, no other livestock)

Both are reefs and i have also read that they steel food from corals, can irritate them quite bad or is this not the norm but the exception?

Thanks
