Alex Mustard - Unicorns
These unicornfish are gathered for mating. They are surprisingly large fish (60cm) and usually live solitary. They only gather in schools during the mating season. Even so, you need quite a strong current running to get them as neatly lined up as this. So I was swimming very hard into the current to get ahead of them to make this photo!
I prefer this photo in black and white, although it is published much more regularly in colour.
