I got an "African leaf fish" from petsmart almost 2 yrs ago. I found out later that the correct name is Spotted Climbing Perch though. Here is a pic of him when he was in my qt tank a while back. He was about an inch to 1.5in when I got him and now he's about 6 in long. If that's what you saw it's a cool fish, really chill and doesn't bother anybody. I love mine!
