ok ill be sure to watch, so far i just see aggression with the big endli once in a while he snaps at my small endli and ornate, or hell grab their heads with his mouth then lets go. im sure that its territorial and maybe the big endlis hungry. hes starting to eat more food and being more active so that means hes too busy swimming to bother the endli and ornate. also think hes still getting used to my tank.
