General information

The Blue Devil Fish, scientifically known as Paraplesiops poweri, is a captivating marine species admired for its striking blue coloration and intriguing behavior. This species is a member of the family Plesiopidae, commonly referred to as the longfin family. The Blue Devil Fish is not as commonly found in the aquarium trade as some other marine species, but it is highly prized by enthusiasts who appreciate its unique appearance and personality.

Care

Caring for the Blue Devil Fish requires a well-established aquarium with plenty of rockwork and hiding places, as they are naturally reclusive. They thrive in environments that mimic their natural reef habitat. A varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood is essential for their health. Due to their shy nature, they may need to be fed more frequently in smaller amounts to ensure they are getting adequate nutrition.

Reproduction

In the wild, Blue Devil Fish are known to be cave spawners, laying their eggs in protected areas within the reef. In captivity, breeding is rare, but with the right conditions, it is possible. The male typically guards the eggs until they hatch.

Habitat

Paraplesiops poweri is endemic to the temperate waters of eastern Australia, often found in rocky reefs and caves. They prefer habitats with ample crevices and overhangs where they can seek refuge and hunt for small invertebrates. Their depth range is usually between 5 to 40 meters.
