holy geez, violent fish! I have an SAE, and its no fluke that its in my pic...I love him/her... it likes to "sit" on its fins, and sort or hop, or almost walk around as if it were becoming amphibious or something, really funny to watch, and great with algae...he himself, fully matured cleaned up a fair sized log covered in BBA in 3 days...and hes not at all violent...I had a Chinese algae eater on the other hand that killed 4 fish..maybe you have a CAE?
