benzjamin13;781437; said:The African Brown Knife is a pretty shy fish. An Oscar can easily bully it. The Clown Knife is a bit more aggressive than an African Brown Knife (even if both fish are pretty mellow, IMO) and can hold it's own against fish like an Oscar. I've seen tanks with different speices of Knife fish and they don't end very well.
