Hi guys, it seems like my synodontis eupterus is bullying my endlicheri bichir, I see it sometimes trying to "nibble" on the rear of the endli, and I was told that my endli has some sort of wound right now, what can I do to prevent the bulllying or do I need to separate the catfish? thanks guys, BTW the endli is around 16-18" and the catfish is 5-7" in length.
