General information

The Longspine Squirrelfish, Neoniphon argenteus, is a nocturnal species known for its bright silver body and long, sharp dorsal spines. It is a member of the family Holocentridae, which are commonly referred to as squirrelfishes due to their large eyes and squirrel-like appearance when viewed from the side. These fish are relatively hardy and can be a good choice for fish-only or larger reef aquariums.

Care

Longspine Squirrelfish are relatively easy to care for but require a tank with plenty of hiding spaces due to their nocturnal nature. They are not aggressive towards most tank mates but can be territorial with their own kind. It's important to keep them in a spacious tank to prevent territorial disputes. They accept a variety of meaty foods, including frozen and live offerings.

Reproduction

In the wild, Longspine Squirrelfish are known to spawn by releasing eggs and sperm into the water column, where fertilization occurs externally. In the home aquarium, breeding is rare, but providing a stress-free environment with plenty of space may encourage spawning behavior.

Habitat

Neoniphon argenteus is found in the Western Atlantic, from Florida and the Bahamas to Brazil, including the Gulf of Mexico and the Caribbean Sea. They prefer reef environments and are typically found at depths ranging from shallow waters to over 180 feet deep. They are often seen hiding in crevices during the day and venturing out at night to feed.
