Berghia verrucicornis are nudibranchs that eats only Aiptasia.
They can be easily subject to predation (by shrimps -peppermint shrimp included- and other inhabitants).
Powerheads are other concerns (like most of the nudi's).
Proper acclimatation in a sump is highly recommended.
But what happen once the Berghia have consumed all the Aiptasia? It'll starve to death.
Although they have a short lifespan, they are hermaphroditic and reproduce in reef tanks as long as they have enough Aiptasia.
A good idea can be having 2 o 3 rotating between members with aiptasia problems.

$ 15 + shipping overnight 20 to 30 Fedex.
If you buy less than 7 add $ 4 box charge.
If you buy (GB or something) from 30 to 44 berghia, shipping free and $ 14/berghia.
I know there was group buy done not too long ago by deepwater and want to know if anybody is will ing to sell me their bergi when all their aptasia's are gone.
Don't waste your time time with this crap. I bought some along with another MR reefer & it did not do squat for the both of us.
Here is another example where greed has taken over & they try to sell you these ridiculously small & immature nudi's. They have a much lower survival rate than mature ones. My aiptasia could swallow them without any problems, wihich is probably what happened. I did manage to see 1 of them about 2 weeks later & it had grown. It has not made a single dent in my aiptasia population & it most likely got killed off too.
I know of several people that have used them with success. The problem in 99% of the failures is lack of patience. It takes an AWEFUL LOT of patience to get the culture going and to properly acclimate them to a system.
If you buy one of those three packs you would need to culture them for about a month before you can start adding them to your main system and it will take a good month before you see results in the system.
I would be interested in acquiring a few adults myself...
