The confusion and myth about 2 different peppermint shrimp is basically a problem with common names. The true peppermint shrimp, Lysmata- are the ones who eat the aip's. The other shrimp in question are "camel" shrimp, please forgive me I don't know the latin name.
That said, I usually hit them with joes juice and keep a couple peppermint shrimp on staff full time. Joes juice seems to get clumped up and clogs the syringe days after initial use, adding RO water doesn't seem to help, just a heads up.
Peppermints are a better choice than berghia as the berghia will always need aips to live. They will eradicate all that they can find, and then die, only to have a small piece behind that flourishes into an aiptasia forest. This can be avoided if you've got friends/reef club that you can pass the berghia around with to keep them alive. Peppermints however, will eat all kinds of stuff in the tank, and you won't have to deal with the ramifications of keeping the expensive nudi alive.
