I've had my ex try to surprise me with a Senegal in my ornate tank..... lets just say it got eaten before I even got to see it lol
I think ornates are probably the most likely upper jaw to eat smaller poly, when I got my DAT I put my 6 inch polli in the main tank from the grow out, and my 8 inch ornate was still trying to eat him the nest day so its back in the grow out for him
You'll be fine, I've grown out a VERY small albino Senegal with that Polli, never nipped it or lunged at it. That I saw at least lol. Albino is around 2.5-3 inch.
You'll have to be a bit more careful w/ the endli, I would put it in the main at 5 inch, by then it should be plenty thick enough to not be eaten
