Thank you. I purchased them from the original owner in March, and since then they have really colored up and put on size quickly. The previous owner purchased them from stingray biology in 2019. The short tail is the male the other 3 are female. When I purchased them I was told that a tiger shovel nose had mistaken his tail for food which resulted in a barb through its nose and part of his tail missing. His barb has started growing back, but I’m unsure if his tail ever will.
