Flame Hawkfish
Neocirrhites armatus
The Flame Hawkfish is one of the most distinctive and charismatic members of the hawkfish family. Its brilliant scarlet-red body, contrasting black markings along the dorsal fin and around its eyes, and alert, inquisitive expression make it a striking addition to a marine aquarium.
Native to the tropical reefs of the Pacific Ocean, this fascinating species spends much of its time resting among branching corals, rockwork and elevated ledges. Rather than swimming continuously through the water column, it prefers to perch on a favourite lookout, watching the aquarium for movement before making a quick dash to investigate food or a passing tankmate.
Like other hawkfish, the Flame Hawkfish lacks a functional swim bladder and uses its strong pelvic and pectoral fins to support itself while resting. Its unusual perching behaviour gives it an almost watchful, bird-like personality and makes it particularly entertaining to observe.
Once settled, Flame Hawkfish often become bold and confident aquarium residents, readily recognising feeding activity and moving between their favourite perches. Their vivid colouration stands out beautifully against natural rockwork and colourful reef corals.
Although generally compatible with corals, the Flame Hawkfish is a natural predator of small crustaceans and should not be considered safe with ornamental shrimp, small crabs or other vulnerable invertebrates. It may also show territorial behaviour towards small, peaceful bottom-dwelling fish.
With its brilliant colour, unusual habits and engaging personality, the Flame Hawkfish makes an impressive addition to a carefully planned marine aquarium where its natural predatory behaviour can be accommodated.
Feeding Notes Flame Hawkfish are carnivores that naturally hunt small crustaceans and other invertebrate prey among reef structures. Provide a varied diet of frozen mysis, enriched brine shrimp, chopped marine prawns, finely diced marine fish and other suitable meaty foods. High-quality marine carnivore pellets may also be accepted once the fish has settled into aquarium life. Feed small portions once or twice daily, ensuring food reaches the fish's preferred perching and feeding areas. Flame Hawkfish are typically enthusiastic feeders once established and may quickly learn to associate their keeper with feeding time. A varied diet is important for maintaining good condition and vibrant colouration. However, regular feeding does not eliminate their natural hunting instincts, and well-fed individuals may still prey on ornamental shrimp or other small invertebrates. Aquarium Setup Notes Provide a mature, stable marine aquarium of at least 150 litres with established rockwork, numerous elevated perches, sheltered crevices and sufficient space for other fish to establish their own territories. Flame Hawkfish naturally inhabit shallow, well-oxygenated reef environments, frequently resting among branching corals or on rocky ledges. A well-structured aquascape should provide sturdy resting points at different heights, together with sheltered retreats. Moderate to strong, varied water movement is appropriate, provided the fish has access to sheltered resting areas away from continuous direct flow. Good water circulation, oxygenation and stable water quality are particularly important. Lighting can follow the requirements of the aquarium's other inhabitants. The Flame Hawkfish is adaptable to normal reef aquarium illumination and will appreciate areas of shade beneath rockwork or overhangs. A secure, tight-fitting aquarium lid or mesh cover is essential. Flame Hawkfish are capable jumpers, particularly when startled or during rapid feeding responses. Although they frequently perch on coral branches in their natural habitat, provide alternative rockwork perches in reef aquariums to reduce the risk of repeatedly irritating delicate coral colonies. Compatibility Notes Flame Hawkfish are generally bold, territorial fish that can coexist successfully with suitably sized, confident marine species. Potential tankmates include clownfish, larger wrasses, tangs and other robust community fish that are not easily intimidated. They may become aggressive towards smaller, peaceful bottom-dwelling fish, particularly gobies, blennies and dartfish that occupy similar areas of rockwork. Very small fish may also be at risk of predation. Best kept singly in most home aquariums. Flame Hawkfish may aggressively defend their preferred resting areas against other hawkfish or similar territorial species. Compatible pairs are possible under appropriate conditions, but two unrelated individuals should not automatically be assumed compatible. Reef safe with caution: Flame Hawkfish do not normally feed on living coral tissue and can be maintained in many coral-dominated aquariums. However, their habit of perching may irritate delicate coral polyps, particularly when they repeatedly rest on the same colony. The greatest compatibility concern is ornamental invertebrates. Flame Hawkfish are natural predators of small crustaceans and may attack or consume ornamental shrimp, including Peppermint Shrimp and Cleaner Shrimp, as well as small crabs, hermit crabs and other vulnerable invertebrates. Feather duster worms and small snails may also be at risk. Larger, established invertebrates may sometimes coexist with individual Flame Hawkfish, but their safety cannot be guaranteed. Regular feeding does not remove this risk. Careful tankmate selection is essential, particularly in mixed reef aquariums containing valuable ornamental shrimp or delicate, slow-moving fish.
