| I have the book also and remember reading that part. No clear explanation as to why that is, but many factors may be involved, not just that tap water may be better for anemones. I don't recall her stating what husbandry approaches were recorded or the actual water quality of each tap water respondent. I think her study was more correlational rather than cause-effect. In other words, the tap water may not have been the actual reason for the success of the anemones. And remember, the study was actually done a few years ago ( I think first publication of the book was in 1996) and I think only 100 people or so took the survey. Again, too many other reasons why the results came out as they did. I hope I am making sense.
