I have an infatuation of Majano anemones in my reef. I have tried everything from limewater to Joe’s juice and nothing works.

They go away for a few days then three or more pop up where the original was. I have a Stars and Stripe Puffer in a 100 gal fish only tank and he eats these things like candy. Question is if I put a few rocks from the reef in his tank at a time and let him eat them will they make him sick? He has only eaten two or three that were already in his tank and they did not seem to bother him after he ate them.
