The RRC Angry Birds Tenuis is an extremely rare piece that is one of the most desirable acropora in the hobby. This piece gets bright red polyps outlined with yellow and orange corallites, backed by a light blue and green base. There are three main types of Angry Bird Acros, the RRC (Reef Raft Canada), RRU (Reef Raft USA), and RRA (Reef Raft Asia). This specific piece is the RRC Angry Birds, one of the least common of the three.
