Okay, I have read all this, and still do not know how to proceed for my 25 gallon tank. I have used Aptasia X with the same success as jeep. Now I have them multiplying and growing beyond control. I tried peppermint shrimp (true) on 2 separate occasions. First 3, then 2 more. Each time they lasted 3 days or less. Either the Yellow Tang, the Strawberry Pseudochromis, the Clown (highly unlikely) or the Dragon Goby ate them. I've been told that any fish will also eat the coral. There are too many now to attack one by one. Some are in places I would never be able to get to them sufficiently. My next step, I think, is the Berghia Nudi's. Looking for advise and the best place to get them...price is important too. Thanks!!!
