I imagine you could see shapes and shadows plus the fins but yea close details would be hard to see without viewing panelsI find this topic very interesting, but don't have anything to add about the care. I did have a question though. Based on this thread it seems these sharks need a lot of flow. In a pond setting with significant flow would you really be able to see the sharks from an aerial view? Wouldn't the high flow make the water very choppy for viewing? We're you planning or able to add side viewing panels.
