A stingray that’s similar to the Eclipse is the Black Diamond stingray. This ray looks very much like the Eclipse, but has a few subtle differences. For starters, it has a much darker body and brighter white spots.Additionally, this Stingray has white spots around the eyes, as well as a double row of spots on the edge of its disk. Some of the spots found on the Black Diamond even form shapes and letters! The Black Diamond species is another great option for a freshwater stingray. It’s more affordable than the Eclipse, but is just as fascinating and beautiful.
