How do you care for the flame hawkfish?

Mostly peaceful but predatory.

Feeding

Carnivore.

Meaty foods.

Tank and special needs

Plan for at least 114 litres of water (the care sheet says 30 US gallons).

Perches on rock and coral.

Corals and invertebrates

Small shrimp; small bottom-dwelling gobies and blennies.

Which tankmates suit the flame hawkfish?

No small shrimp or tiny fish.

Suggested order in a mixed tank: add last, after the peaceful fish have settled.

More than one flame hawkfish

Keep one flame hawkfish: two of the same species usually fight.

Other fish

Checked against the other 59 fish in this guide, assuming a tank big enough for both. Individual fish differ, so treat this as a starting point.

Avoid together (3)

  • Yellow clown gobyFlame hawkfish can swallow a fish as small as the yellow clown goby.
  • Longnose hawkfishBoth are hawkfishs of similar shape, which is a common trigger for fights.
  • Falco hawkfishBoth are hawkfishs of similar shape, which is a common trigger for fights.

Take care (1)

These checks follow the reasons fish and invertebrates clash: same species or genus, similar shape, mouth size, temperament, food, burrows, tank size and the order they are added. Individual animals differ; every source agrees on that.

Quarantine and health

Hardy.

New fish are the most common way disease gets into a reef tank. Quarantine every fish in a separate tank before it joins the display, and choose a method that suits its tolerance of copper.

Captive-bred or wild?

Wild-caught.
