cichlids are rather notorious for being territorial/aggressive. I've had a small 2cm female apisto (not defending any brood, by the way) terrorize 9 altum angels. Wherever she went, the altums had to avoid her or she'd charge at them. These altums weren't wimps either. They killed and ate 1/2 of the ember tetras I put in that tank overnight and I was forced to remove the rest. They have also since eaten 100+ cardinal tetras in another tank, and are dominant over my discus as well
i love cichlids![]()
