So I got 3 Berghia Nudiabranchs about an month ago and I put them into my tank to deal with Aiptasia and the Aiptasia amount has not been decreasing and I have not seen my Berghia Nudiabranchs since I added them. What do I do because I really need the Aiptasia gone but everything I have tried has just failed I have tried peppermint shrimp and Aiptasia x I just hoped Berghia Nudiabranchs would be the end.
