Mine did great, though they ran out of food and most died, I believe. The other day, while doing some maintenance, I did find one that was alive and huge. I moved it to a tank where it can find more food. After our group buy, I ran across some additional information. It seems that their color indicates their health. When healthy, they are a light brown/gray color, as all of ours were when delivered. As they run out of food, their color lightens up. They will eventually turn pure white, which is an indication that they're starving. I wish I'd have known that sooner, because, for awhile, there was one that we kept spotting in Angie's Nano, that was lightening up, and eventually turned white. The tanks that we put the Berghia in are still free of any aiptasia. I never saw any lay eggs, or any young. However, I put most of ours in a rubbermaid tote with a lot of aiptasia infested live rock. I wouldn't be at all surprised if they laid eggs in that tote and if there are young in there. I don't pay a lot of attention to that tote except for minimal maintenance....lol. In fact, that's where I found a large, healthy one the other day.
