Pterois radiata

Datasheet

General Description:
The Radial firefish, scientifically known as Pterois radiata, is a member of the Scorpaenidae family, also referred to as the Lionfish family. These striking fish are renowned for their unique appearance and behavior, characterized by their venomous spines and predatory nature. They typically reach a maximum size of around 24.0cm and are native to the vast waters of the Indo-Pacific region, spanning from the Red Sea to Sodwana Bay in South Africa, and further extending to the Society Islands.

Aquarium Suitability:
Considered suitable for aquariums with proper care, Radial firefish are classified as peaceful in temperament but can display predatory behavior towards smaller tank mates. Their hardiness makes them a popular choice for hobbyists, especially those experienced with managing venomous species. However, caution must be exercised due to their highly venomous nature, thus making them only suitable for advanced aquarists.

Demands, Care, and Hardiness:
Radial firefish demand meticulous care and attention in captivity. They thrive in aquariums with sufficient overhangs and caves to mimic their natural habitat. These fish often become tame over time and can recognize their owners, but their venomous spines necessitate careful handling. With a hardy nature, these fish require a medium-sized tank of at least 200 liters, maintained at stable water conditions with a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature range of 22.2-25.6°C.

Reef Suitability:
Categorized as reef-safe with caution, Radial firefish can coexist with corals and other reef inhabitants if introduced carefully. Their predatory instincts may pose a threat to smaller crustaceans within a reef setting, warranting attentive observation when housed in a reef aquarium.

Aquarium Setup:
When setting up an aquarium for Radial firefish, it is crucial to provide ample hiding spots, such as overhangs and caves, to ensure their comfort and security. A minimum tank size of 200 liters is recommended, along with a suitable substrate resembling their natural habitat, either coral gravel or fine sand. Maintain stable water parameters and create a varied diet plan to meet their nutritional requirements.

Behaviour:
Radial firefish exhibit peaceful behavior towards tank mates, but their predatory instincts make them opportunistic feeders capable of consuming prey nearly their size. Care should be taken while handling these fish due to their highly venomous spines, necessitating caution during maintenance tasks within the aquarium.

Feeding and Diet:
In terms of feeding, Radial firefish require a diet consisting of live fish, larger crustaceans like shrimp and crabs, and other nutritious offerings. Some individuals may initially reject "dead" food but can be trained to accept it with patience. Feeding them a couple of times a week with whole, nutritious live foods like Mollies, Guppies, and Ghost shrimp is recommended to ensure optimal health.

Dimorphism:
Dimorphism and captive reproduction of Radial firefish are aspects not extensively discussed in available information. However, their distinct appearance and captivating behavior make them a sought-after addition to many marine aquariums worldwide.

Habitat and Distribution:
In the wild, Radial firefish inhabit the diverse marine environments of the Indo-Pacific region, ranging from the Red Sea to the Ryukyu Islands and as far south as New Caledonia. Their preference for overhangs and caves in reef structures reflects their natural habitat, where they utilize these features for shelter and hunting purposes.
