Thing is if you make them upset they will release larva, also even with the kalk a lot of time you have to cover them up every couple of weeks. Also for anemone, if their system has been up and stable for over a year then you might try a sebea but they are harder to keep, you might try a bubble tip but its hit and miss if they will host it. Anemones are difficult to keep to say the least, and usually end up dieing a long slow death. My bubble tip I had for 3 years, which for an animal that can live for hundreds of years is sad. I had a condy that no other fish would go near, it got too aggresive and huge and I took it to my lfs, that thing got a foot across and kept going close to the powerhead, it had a powerful sting.
