The Hawkfish species are predatory fish, and their companions should be chosen with some thought about their respective sizes. Disparately sized fish may well become hunters and the hunted! Hawkfish will usually favour a particular perching spot in the aquarium, and do not spend any length of time swimming from that perch, or off the bottom of the aquarium.
The Longnose Hawkfish (oxycirrhites typus) is a favourite of this interesting family. It prefers to have a gorgonian coral – real or artificial – to regard as its territory, as the latticed patterning of its body is designed to blend with such a background in nature.
The Flame Hawkfish (neocirrhites armatus) has a deep red colouring with some black markings, and a “chunky” body unlike the more elegant body shapes of the other aquarium hawkfish. But like other hawkfish it sits on top of, or inside, corals and other sessile invertebrate life, making a nice feature for the reef tank. But it is predatory on smaller fish, so needs care when selecting companions.
