I have sold and traded lots of frags at these meetings. I like to post what I have before because folks can see what I'm bringing. I also give them the chance to reserve beforehand by paying. I don't want to cut up 10 frags of Tyree $500 efflo only to trade or sell 2 of them. I would rather know how many are sold, bring a couple extra based on what interest was shown and leave my mother colony in tact as much as possible. Also by prepaying, folks know that they have that rare coral reserved for them, it's not first come first pick. I bring only corals that I have grown out from frags and sell them for much less than you would pay online or at a fish store.
