How effective are Berghia slugs for aiptasia?

[DrDNA]

I have some Aiptasia in my tank and I am getting tired of constantly zapping them. I have been using 2N NaOH which is quite effective, but am looking for something a little more hands-off. What are peoples' experiences with the Berghia slugs? Worthwhile, or mostly hype?

I don't have first hand experience, but anecdotal evidence seems to be positive. When I was dealing with them (aiptasia), I held back as berghia are obligate aiptasia eaters and will starve in the absence the devils. Early in my reefsearch I was brainwashed with the notion that when nudi's die there is much sadness. Don't know if this is true of berghia's as well.
