I hope that will work, some sen get stunned at 5”-8”, some will grow 9”-10” but rarely will grow 12”. If it even gets to 9” mark it will take years before hitting 11”-12”. Most people would go for Lower Jaw species when they want a oscar or peacock setup cause a LJ poly will have a huge size difference in growth compared to a senegal.
See I wasn't sure what species he was until after I got home and researched it.. I was hoping he'd pack on more size than just 8-9inches lol well I guess I'll do some more digging and maybe I'll find a website that sells other types of Bichir.
