At least a dozen would be good, although some say that schools of 18+ are needed to really curb aggression.
+one. Would also note ,that there isn't much that swims that is quicker at snatching food from the surface with possible exception of danios. Would make it difficult for some slower mid dwellig fish to compete at feeding time.
