Common name: Black squirrelfish

General information

The Longspine Squirrelfish, Neoniphon opercularis, is a member of the family Holocentridae. This species is known for its striking appearance, characterized by a bright red body with white spots and long, sharp dorsal spines. They are nocturnal predators, feeding primarily on small crustaceans and zooplankton.

In the wild, these fish are often found in schools, taking refuge in caves and crevices during the day and actively foraging at night. Their large eyes are adapted to low light conditions, enhancing their ability to hunt in the dark.

Care

Longspine Squirrelfish are moderately easy to care for in the home aquarium. They require a tank with plenty of hiding places and a peaceful environment, as they can be shy and easily stressed by aggressive tank mates. A varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood will help maintain their health and coloration.

It's important to note that their long spines can become entangled in nets, so care should be taken when handling these fish.

Reproduction

In the aquarium, breeding Longspine Squirrelfish can be challenging. They are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic and can be difficult to raise due to their small size and specific dietary requirements.

Habitat

Neoniphon opercularis is typically found in the tropical waters of the Western Atlantic, from Florida and the Bahamas to Brazil, including the Gulf of Mexico and the Caribbean Sea. They inhabit coral reefs and rocky outcrops, usually at depths ranging from 2 to 20 meters.

Their preference for complex reef structures with ample hiding spots should be replicated in the home aquarium to provide a sense of security and natural habitat.
