If you have, what has your experience been? Can they be added to a tank with Hermits or will the Hermits attack it/them? I really need to get a Berghi Nudibranch because my Aiptasia problem is out of control. I've used Joe's Juice but they come back so fast and there are so many that I simply can't reach unless I completely tear down my rock wall.:help: Peppermint Shrimp won't work in my tank because of my Eel. I added a Peppermint Shrimp to my tank last weekend just to see if it would eat some Aiptasia and my shrimp was gone within the hour.
