The famous Oregon blue tort, quite possibly the bluest acropora of them all.  This very old school captive grown coral (with many imposters) but we can all agree that none are as blue and as hardy as the original. This is an acropora that has been elusive for many years with only fragments of a single colony first imported years ago.  This acropora is still one of the favorites among coral collectors and farmed by only a few coral propagators to fill the demand.  A waiting list is usual and typical for some of these old school captive grown and propagated corals but well worth the wait.
