Common name: Longjaw squirrelfish
General information
The Longspine Squirrelfish, Neoniphon marianus, is a striking species known for its vibrant red color and elongated dorsal spines. It is a nocturnal fish, hiding in crevices during the day and emerging at night to feed. This species is relatively hardy and can be a good choice for fish-only or larger reef aquariums where its behavior and coloration can be appreciated.

Care
Longspine Squirrelfish require an aquarium with plenty of hiding places and a peaceful environment. They are not aggressive towards other fish but can be territorial with their own kind. It's important to provide a varied diet consisting of meaty foods such as shrimp, squid, and marine fish flesh. They can grow up to 18 cm (7 inches) in length, so a larger tank is necessary to accommodate their size and swimming needs.
Reproduction
In the wild, Longspine Squirrelfish are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. In the home aquarium, breeding is rare, but providing a stress-free environment with optimal water conditions may encourage spawning behavior.
Habitat
Neoniphon marianus is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They prefer coral reefs and rocky outcrops, typically at depths ranging from 3 to 35 meters (10 to 115 feet). In the aquarium, replicating their natural habitat with live rock structures will help them feel secure and display natural behaviors.
