veriann, my wife was thinking that the Aiptasia was a "bonus" that came on one of the rocks that was home to another coral. I must confess I thought it was cool until there was a forest of them one that one rock. I know I was getting into trouble when I found 5 Aiptasia growing on a powerhead power cord. I am very thankful for Joe’s Juice and I will recommend it to anyone who has an Aiptasia outbreak. I guess I really need to learn how to find hitchhikers before they take over the tank.
