I order the Berghia Nudibranch in Feb. I have a 135 gal tank that was being over run by Aiptasia. Nothing happened for 5 months, then in the last 3 weeks I noticed the aiptasia starting to disappear. From what I can see there are two left, I have seen a nudi out when my lights dim. It took some time but they did the job.
