Common name: Weedy scorpionfish

General information

The Weedy Scorpionfish, scientifically known as Rhinopias frondosa, is a highly sought-after species in the marine aquarium trade due to its unique appearance and behavior. This species is part of the Scorpaenidae family, known for their venomous spines and ability to blend into their surroundings. Rhinopias frondosa is particularly admired for its elaborate frilly appendages and striking color variations, which can range from reds and purples to yellows and browns.

Care

Rhinopias frondosa requires a specialized care regimen due to its unique needs. They are sedentary ambush predators, preferring to remain stationary and blend in with their environment until prey comes within striking distance. In the aquarium, they need a well-structured setup with ample hiding places and a sandy substrate. They are not active swimmers, so a moderate water flow is sufficient. Feeding can be challenging, as they typically prefer live food, but with patience, they can be trained to accept frozen or prepared foods.

Reproduction

Little is known about the reproductive habits of Rhinopias frondosa in the wild or in captivity. They are presumed to be egg layers, with external fertilization. Breeding them in the home aquarium is considered extremely difficult and is rarely achieved.

Habitat

In the wild, Rhinopias frondosa is found in the Indo-Pacific region, often associated with coral reefs and rocky outcrops. They are adept at camouflage and can be found at depths ranging from shallow waters to over 90 meters. Their cryptic nature makes them a challenge to spot, even for the most experienced divers.
