I am looking for 4 or 5 Berghia for my aiptasia issue in a 70gal. I see them online but shipping costs makes it too pricy for a handful. Looking for others that are interested in buying some. Reeftown.com offers free shipping for orders over $299. So 5 people going in ~$62 each will get you 4 med nudi. (Not sure if they charge tax). You may want more so fewer people needed for free shipping limit.
I have no affiliation with this company nor have I used them. I am assuming they are legit. Some good reviews on reef2reef.

Thanks and let me know if there is interest and how many?
