I just want to report that the last of Aiptasia disappeared yesterday. Thank you so much for your help, we were a bit worried at first but one by one the Aips were missing from the tank. The last to go was the first we had spotted months ago (in the back of the tank) and was the subject of many attempted kills prior to your Berghia. Thanks again.

Though skeptical, I purchased a dozen medium berghia nudibranches for a 300+ Aiptasia epidemic in my 144 gallon Reef tank. Did not notice any action for first few weeks, then population began decreasing and now a month later there isn't a single Aiptas...
