Trumpetfish are one of my favourite fishes. They are long, sometimes almost a metre, and have a snout that almost looks like a horse. They belong to the same order as seahorses and coronetfish. They come in an assortment of colours. My favourite is the one with the blue snout, pale body and blue tail.
They often hover in the water vertically and can move into a gorgonian sponge vertically, deftly avoiding the branches.
