Ok sweet makes my tank that little bit special lol, I'm guessing the open coral program in trading frags??
there's a special forum for the Open Coral Program so you can learn about it and its goals but basically, its to help as many different types of coral be spread out to as many different tanks as possible. Its a form of conservation.
New corals and new variants on known corals are turning up all the time. Just say a diver collects a zoa he's not seen before and sells it to a dealer. The dealer passes it on to an LFS and you come bopping along and see it - awesome coral you've never seen before, must have it! So you buy it. But several months later, there's a power outage and your tank crashes. You lose all your corals including that really special one that you haven't been able to ID because its so new, no one's seen one like it before. After a few years, you see another one but this time it's named and costs a mint - turns out its a rare mutation that doesn't occur often and is hard to find in the GBReef.
Now, just imagine you'd fragged that zoa and donated 2 or 3 pieces to the OCP. The coral wouldn't be lost to you or the entire marine hobby. Its a way of helping your fellow reefers get new and interesting specimens into their tanks and to spread the gene pool. :)
