As in Phenacogrammus interruptus? Lovely looking fish; pretty robust; can become chunky ~10cm fish as adults to a 4-foot tank is preferrable; good schooling fish for African oddball tanks inclding Butterfly Fish/ Leopard Bushfish etc. as they are generally quite calm moving/feeding fish; best to stock 1 male to at least 2 females so I'd personally go for a group of 9 with 3 males (so the males will display their amazing colours to impress the females and challenge their rivals).
