Zoa colonies have about 50 polyps or more. I have several smaller colonies not pictured. Green and red monti mounted to a piece of rock. There is a small RBTA attached that can go with it or be removed easily. Also a small individual RBTA. Looking for SPS or neon green zoas. Might consider something else. Just looking to change things up and this monte is getting to big for my tank. I am also looking for small fish for a 30 gallon tank. I live in New Carlisle right outside Dayton. Sorry for the blued out pictures.
