Looking for berghia nudibranches for my Aiptasia problem

[monocus]

you can take them out of the tank after they have cleaned up the aptasia and give or sell them to someone else-best done at night when they are active.they can go without food for 7 days.aptasia will always crop up again even after the berghia have done thier work-either from introduction of new coral or just one daughter cell in the water collumn.i don't mind aptasia in my overflow or my sump as they clean the water.you can also try a small bannerfish for aptasia on top of the rock
