It looks Like I am going to be getting a polypterus ornatipinnis and a polypterus palmas polli from rehobothaquatics. I understand that the Ornate Won't be able to live with my sens and the palmas forever but about how long will I have given all of them at approx. 6-8inches before the ornate could start to see his roomates as oversized spaghetti? I have plans and most of the cash for a 150-200 gal tank and will be moving the Ornate to it, just need to know how long I have before I need to have everything ready.
