The Ignitus Anthias, Nemanthias ignitus, is hermaphroditic meaning all are born females, and when needed the dominant female turns into male. They also display sexual dimorphism though they have the same coloration of an orange body accented with yellows and reds along the fins and tail, though the male is much more vibrant than the female . They can be kept as a mated pair, or in a small school of females. Avoid keeping two males in the same tank, as it can lead to extreme aggression.

They are hardy and peaceful and can be kept in a reef tank setting with plenty of live rock. Diet should include a variety of a steady supply of copepods, frozen mysis and vitamin enriched brine shrimp, as well as high quality flake foods 3-5 times daily.

Ignitus Anthias Habitat:

The Ignitus Anthias, commonly known as the Flame Anthias, originates from the Indo-Pacific region. These vibrant fish inhabit coral-rich areas, where they can find shelter among the coral branches and explore the reef's crevices. They are often found in shallow to moderately deep waters in the wild.

Reef Compatibility of Ignitus Anthias:

The Ignitus Anthias is considered reef-safe, which means it is generally compatible with various coral species and other reef-dwelling invertebrates commonly found in reef aquariums. However, monitoring their behavior is essential, as they can become territorial, especially during feeding times.

Size of Ignitus Anthias:

Ignitus Anthias typically reach a size of about 3 to 4 inches (7.5 to 10 centimeters) when fully mature. This relatively small size makes them suitable for many aquarium setups.

Lifespan of Ignitus Anthias:

With proper care and a suitable environment, Ignitus Anthias can live for an average of 5 to 7 years in captivity, making them a long-term addition to marine aquariums.

Diet in Captivity:

Ignitus Anthias are naturally carnivorous and predominantly feed on zooplankton and small crustaceans in the wild. To maintain their vibrant coloration and overall health in captivity, it is crucial to provide a varied diet that includes:

  • High-quality marine flake or pellet foods
  • Frozen or live foods such as brine shrimp, mysis shrimp, and copepods
  • Offer small, frequent feedings throughout the day to ensure they receive adequate nutrition.

Aquaculture Availability:

Ignitus Anthias are commonly available through aquaculture efforts, making them a sustainable and responsible choice for marine aquarium enthusiasts. Captive-bred specimens are generally more adaptable and less stressed than wild-caught fish, which is advantageous for their successful acclimation to aquarium life.

Sexual Dimorphism:

Ignitus Anthias exhibit sexual dimorphism, with males and females displaying distinct coloration and size differences. Males are typically larger and have brighter, more vibrant colors, including a striking yellow dorsal fin, while females are smaller and exhibit a less intense coloration.

Symbiotic Relationships:

In their natural habitat, Ignitus Anthias form symbiotic relationships with coral structures. They often seek shelter and security among the coral branches, protecting themselves while potentially benefiting the coral by deterring coral predators.

Juvenile vs. Adult Coloration:

Juvenile Ignitus Anthias exhibits a more subdued coloration, with a pale orange or yellow body. Their colors intensify as they mature into adults, and males, particularly, develop the characteristic fiery red-orange dorsal fin.

Compatibility with Other Fish:

When considering Ignitus Anthias for your saltwater aquarium, compatibility with other tank inhabitants is crucial to maintaining a harmonious environment.


Ignitus Anthias are known for their peaceful temperament, which makes them suitable for community aquariums. However, providing ample hiding places is essential, and ensuring that more dominant or aggressive species do not intimidate them during feeding is necessary.

  • Cleaner Shrimp (Lysmata amboinensis): These invertebrates can contribute to maintaining a clean and healthy aquarium environment.
