General information

The Bluestreak Devil, scientifically known as Neoglyphidodon oxyodon, is a vibrant and active species of damselfish. This species is known for its striking coloration, which includes a deep blue to black body with bright orange to yellow stripes running along the sides. As juveniles, they exhibit a more subdued color palette, which intensifies as they mature.

In the wild, these fish are often found in shallow reefs and lagoons, where they establish territories. They are known for their bold and aggressive nature, especially when defending their space.

Care

Bluestreak Devils are hardy and can adapt to a range of aquarium conditions, making them suitable for both novice and experienced aquarists. However, their aggressive temperament requires careful consideration when selecting tank mates. They do best in tanks with plenty of live rock for hiding and territorial establishment.

A varied diet of meaty foods, herbivore flakes, and pellets will keep them healthy. It's important to maintain high water quality and stable parameters to prevent stress and disease.

Reproduction

Like many damselfish, Neoglyphidodon oxyodon are oviparous, with females laying adhesive eggs on substrates. The males then guard and aerate the eggs until they hatch. Breeding them in captivity can be challenging due to their territorial nature.

Habitat

Neoglyphidodon oxyodon is native to the Indo-Pacific region, from the Andaman Sea to northern Australia and eastward to the Solomon Islands. They are typically found at depths of 1 to 12 meters, in coral-rich areas and rubble slopes.
