The reason I ask is cause I just picked up another lg. aro and his fins are so much darker than all my silvers. Kinda made me curious? The previous owner don't really know much about fish. He said he had it since it lost it's egg sack but he also told me the iridescent shark I picked up off of him was a bala shark.![]()
