Something that worked amazing for me in the past was to buy a syringe with some needles, and I would inject a little bit of vinegar into each one. They died instantly and within a week, I could get em all. Never had a problem with aptasia

I tried this after seeing it suggested on reef2reef. It definitely killed the ones I targeted, but a week later I had twice the amount. I got bhurgia nudibranches shortly after, and they worked great until my wrasse found them

Yeah, you gotta target as many of them as possible, so you can't just kill a couple and leave the rest. I found that if you jab them quickly before they retract it works best.
