Provided the tank is large enough, will Polypterus endlicheri and weeksii make good stingray tankmates? I have kept Ornates before and noticed they are a bit nippy but have not noticed the endlicheri or weeksii biting stuff they can't eat.
I have an endli with my rays but...just recently added this guy... I used to always have a large endli with my old rays as well without a prob in a 300g
