I received a live rock from an acquaintance and a few corals, just not really sure what these are. I never kept any zoas or palys before. I know some if not most can be harmful. Just wondering if these are particularly dangerous or not to bad. (I did transfer them into my tank and briefly exposed them to the air going from bucket to to tank, this was 5 days ago, no issues, I also wore gloves and glasses as a precaution.
