I’m hopeless when it comes to coral names. I think they’re both types of hammer. I doubt either are very rare. The darker one is bigger than fist size. I have a couple heads (10?) of the green one.
I’m mostly trying to find a good home for everything. I have a rock I glued multiple heads of various variety to a year ago. Can be broken up if you prefer otherwise $25 for that group? I’m open to discussion. Not trying to get top dollar on any of livestock. Feel free to PM if you want more images, details, or want to talk about price more.
Equipment I’ll be a little more firm on a price because I can hang onto it and sell later. Livestock needs a good home.
