It's deffinately a carnarion coral and don't worry about logging it because it will be dead in a few months. It was sold to you for the great deal of $20.00 because it is probably already half dead. They go for about $60.00, but should not even be sold in the aquarium hobby. Sorry I don't mean to jump all over you, but it bothers me when people buy things not knowing what they are to just put them in there tank and they will die. It also bothers me more that these things are even sold in the hobby because they will just die. They are beautiful so they sell. Like I said it's not you, but people need to do their research because if we do not buy these things they will not be sold and they will stay alive in the wild where they belong. better luck with your next purchase.
