That must have been an awesome sight. Any chance you have a picture?I know the thread is a little old, but African brown Knifes do great in schools. The main idea though is that you have to have school. Two doesn't work nor does four, but nine or ten works fine. I keep a school of ten in a 240g. The school started with six and I have added the extras over the last couple years. Even new much smaller knifes are quickly accepted into the school.
