I had about 10 that were in a very hard spot to get to and they were damaging a couple of SPS. I got 5 Bergas and in about 2 weeks no sign of aptasia . I am keeping an eye out for the bergs so I can hopefully rehome them so they do not starve

I haven't seen a single aiptasia since I added a filefish a couple of weeks ago. Until then, I was finding 2 or 3 new ones per week.
Unfortunately, it also killed all my RFAs. At least I only had 3 of them.
Rock flower anemonesRFA?
Has anyone tried putting their Berghia in their overflows? If so how did you do it? I just got some today and am in the process of acclimating them. By far the most significant outbreaks of Aiptasia in our tank right now are in our overflows. I just don't know how to place any of the Berghia's in there. I'm worried if i try to place them directly on top of an aiptasia, they will get stung/killed but i can't just drop them in the overflow and let them swim can I?
I believe your worry is justified. Not that you needed it Not having owned any before but have considered them in the past and actually just this week I am in a similar situation. Display has a few but overflow and sump the most. The way I've thought about it is turning off all the pumps, split the order, acclimate accordingly, and place half near the larger pest and the other half in the overflow.
As to where in the overflow I would reach in and juggle around a few pieces of rubble that I keep in there so they can start their journey there. My take is once they settle in they can withstand the overflow volume or so I hope. If I think they are moving around a bit too much then I'll just dial back my returns and let the display tank powerheads do the work.
Slow flow through sump is my general take anyway as it gives the skimmer more time to run through the water. Too fast and it is a lot of noise and skimmer is less efficient. At least in my opinion. My thought in this is that the berghia will work their way through the system to sump or back to display over the weir.
I do not know how the berghia find the pests. Is it like taking a walk or are they using smell or some other sense. I know not but my fear in my display is that I have pukani rock and it has a lot of nooks and crannies so they will be moving around for a long, long while.
Where did you find yours? Most of the places I looked are out. My display picked up again because I got rid of my matted filefish after he went through my frogspawn
I'm not worried about the flow in my overflows, but I don't currently have any live rock rubble in there. May have to try and set a couple pieces and go for it.
As far as how they find it....
"The Berghia nudibranch is also designed to eradicate Aiptasia. The Berghia nudibranch possess specialized sensory organs called rhinophores that are able to chemically detect Aiptasia anemones. This allows the Berghia to target in on Aiptasia, even those anemones too small to be readily seen."
The same person i get my livestock placed a big order for them for a client's tank of his and he ordered some extra for me. Think he got them from salty underground.
I just added 6 berghia to my overflow a couple of weeks ago. I have some pvc plumbing in there with a flat section on top where I could place them with the pipette that came with them. I placed them on the pvc that's under water, of course.Has anyone tried putting their Berghia in their overflows? If so how did you do it? I just got some today and am in the process of acclimating them. By far the most significant outbreaks of Aiptasia in our tank right now are in our overflows.

I covered mine at some point and just the light coming in through the notches seemed to allow them to thrive. Perhaps if the overflow had been covered from the get-go they might not have gotten a foothold though.I would suggest making it so there is no light in your overflow - this MIGHT help control it - even though aiptasia can grow in low light - I do not believe it will grow in 'darkness'.
Hi. From my experience the nudis won’t touch the manjano. I had a crew in a small tank wipe out the aptasia and I was left with 4 manjanos.Has anyone had success with Burghia eating Manjano. I used Manjano Wand several times and all that did was create an explosion of Manjano. I now have a tank full of very happy plump Manjano
