Aptasia on coral

[Foxchase]

So unfortunately i got stuck with some aptasia after somehow one snuck in and has multiplied in my tank.

Now i have a few of them on zoa's and some acans. How can I kill the aptasia without harming the corals?

**** i have wrasses so shrimps will just become an expensive snack. I also have a bunch trachys, lobos and scolys so i don't wanna risk losing them to a rogue filefish***
