My LFS will barely give any store credit. They said they would give me $20 for 100 white pom-pom Xenia frags. So thats 20 cents per frag. It would cost me more for the LR rubble or plugs to grow the frags on. Apparently they harvest frags from their customer's tanks that they service and maintain so they get frags for free. So it isn't just a Xenia thing. They said they would take the frags from me but I'd rather give them away or trade for that price. Problem is I only know one other person in the hobby.
