Question 9

You discover a small reef fish species in the Great Barrier Reef off the Australian coast. You study its ecology and discover that many midsized and large predatory fish consume the new species. Further, you find that this species consumes the same prey as many other species of similar-sized fish. However, many of those other small species tend to live in large schools, whereas individuals of this newly discovered species live alone. Propose a general ultimate hypothesis to explain what ecological conditions could cause a small species to live alone rather in a large school.
