How to get rid of Aptasia outbreak

I have a major outbreak of Aptasia in my tank and know with time it
will damage my coral. I have heard of all types of ways to get rid of
them such as getting peppermint shrimp, getting a syringe with needle
and use it to squirt vinegar into them and as well buying solutions
that you can insert with the syringe. I have tried the latter but
unfortunately when I get close to them they close up so I am not able
to do this. As well, I heard if you break them apart they multiply.
Any suggestions on how I can solve this problem?
