I have tried this with only some sucsess, but I also dont remember where and how many I did it to at one time...LOL But you can try and I still do this when I could get to them other wise that is why I got the same file fish a few days age... Fill a syring up with you ALK dosing fluid get your water change tub all set up stab the aptasia in the neck (not the head or mouth) put a 1/2 cc or more ( I always like more :Up_to_som) in to it as it starts to melt start sucking the crap up with your wc tub....The kind that swim. nah jk kiddin I have a matted leatherjacket filefish (Acreichthys tomentosus) aka bristletail file fish. why do you ask?
