I finally have my 125 up and running and I wanted to add a Fei Feng, but I'm confused about the difference (if any) between S. taeniurus and S. insignis. I've looked at a few different fish reference sites and the only differences I can find mentioned are that taeniurus might stay a little smaller and it keeps its spotting through adulthood. My Aquarium Atlas only mentions that insignis is less colorful. Any help would be appreciated. Thanks!
