Well I am attending my first local reef club meeting tomorrow and they are selling some frags from other member tanks. Any suggestions on bringing new frags into my display from this event? I do not have a quarantine tank. Should I just dip in a commercial coral dip like I do other corals I get from the store? or is there something else I should do? or is it too risky from someone elses tank? I have not read in the past where anyone has had any issues from any previous events.
