I've got a 3.75" senegalus and plan on getting a 6" ornate. (I've not seen the ornate yet, just going on reported length.) Would the two of them be able to growout in a 30 gallon for a while, or would the ornate try to have a snack? I know that ornates are an upper jaw species and don't have the gape of a lower jaw. There is also a chance that I'll be getting a 4" Polypterus mokelebembe at the same time (also reported length). The ornate and mokelembembe are housed together at the moment. Will the three of them get along? Thanks
