G'day mate! They are red bishops...not as red as I would like but their color is improving as they grow..and a nice splash of color in my tank.
The rock was collected from the Maumee River. It is actually a tan brown color but has a nice coating of different color algae growing on it. Eventually all rock ends up the color of the algae growing on it...unless of course you clean it regularly, butvthat a mission I gave up on 2 decades ago...lol
