ok, injected the big one but couldnt get to the smaller ones, so left them to grow abit, then started noticing more little ones popping up all over the polyps. so i phoned the pet store and asked if i could exchange the polyps, they had no problem. so i went there and exchanged it and got a much bigger and prettier polyp coral, and also bought a leather coral, elegance coral, skunk cleaner and more hermits! a simple exchange turned into a pricy visit! will post pics soon! yay they so beautiful!
