Africans are a much easier knife fish to keep. It tops out at around 8 inches, a 55 is enough, and they eat processed food.
Actually, they can get to be over 3'. The problem is that they almost never are given the space that they actually need, so they become stunted in aquaria.iloveengl said:Yep. They get to 18 inches.
