You know what? I had a male EB ram and he would scoot a big angel away from his spot! I don't consider that too bad of aggression. If they bite or injure an angel that's another story, I don't want that. But lol my EBR used to bite my fingers when I got too close to his spot in the fern. He was a fiesty little boi!
You are absolutely correct Tanker, I think it will depend on the structure scape of the tank. I'll try it, depending on what's available. I was looking at EB acara, nannacara or laetacara curviceps. I like the EB acaras bc they are bigger for my larger tank. I could barely see my GBRs from the tetras!
