For a silver, what is the smallest size (length wise) that they could develop DE? I currently have 2 small ones. One is about 5 inches and the other about 6-7 inches. Looks like the bigger of the two is starting to develop DE in it's right eye. Thanks.
My current silver started to develop DE in it's right eye at around 9 inches or so after slamming his face into the top center brace of my tank from being startled by my Oscar.
