I'm not so sure. I have problem after problem with this guy. When I first got him he had a swim bladder problem, then chipped scales,then he got some sort of hole in the soft tissue of his left gill, then my check valve failed on my Prime dosing pump and dumped enough prime into the tank to kill a donkey. My ray and 2 loaches died from the latter. I hope he's like a plant: the harder you try to kill it the harder it tries to survive. Things seem really good right now so hopefully all stays well and I can keep him healthy for years to come. He really does have some potential though I don't think he'll fully cross based on the fact that I've seen several others that are already crossed at much smaller sizes. I won't complain for the price I paid. Despite not providing the greatest conditions, for him to thrive, he's come a long way.
