General Description
The Sapphire Devil, also known as the Cornflower Sergeant-Major or Blue Demoiselle, belongs to the Pomacentridae family within the Chrysiptera genus. This fish species, native to the Indo-West Pacific region stretching from the eastern edge of the Indian Ocean to areas like Western Australia, New Guinea, and the Philippines, is recognized for its vibrant colors and striking appearance.
Aquarium Suitability
The Sapphire Devil, while suitable for aquariums, requires careful consideration due to its aggressive nature. These fish are territorial and can exhibit hostility towards other species that encroach on their space. It is advised to keep only one Sapphire Devil per tank unless in a very large aquarium where territories can be clearly defined.
Demands, Care, and Hardiness
This species is considered hardy and can adapt well to aquarium environments if provided with ample hiding spots such as live rocks. The Sapphire Devil thrives in water conditions with a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and temperatures between 22.2-25.6 degrees Celsius. Regular feeding with microalgae, small crustaceans, and zooplankton is recommended to maintain their health.
Reef Suitability
The Sapphire Devil is deemed reef-safe, making it a viable option for reef aquarium setups. However, their territorial behavior may pose a challenge if other species come too close to their designated areas within the reef.
Aquarium Setup
When incorporating a Sapphire Devil into an aquarium, it is crucial to provide hiding spaces, especially within live rocks. A tank size of at least 100 liters is recommended to accommodate the territorial tendencies of this species and to prevent excessive aggression towards other tank mates.
Behaviour
Known for their territorial nature, Sapphire Devils can display aggressive behavior, particularly towards intruding fish. This aggression is more prominent in males compared to females and smaller individuals. They tend to establish and defend their own territories within the aquarium.
Feeding and Diet
A well-rounded diet for Sapphire Devils consists of microalgae like spirulina, small crustaceans such as krill and mysis, and zooplankton like cyclops. Feeding them multiple times a day with a variety of foods ensures their nutritional requirements are met for optimal health.
Dimorphism and Captive Reproduction
Specific information regarding dimorphism and captive reproduction of Sapphire Devils was not provided.
Habitat and Distribution
In their natural habitat, Sapphire Devils inhabit regions across Australia, Indonesia, and the Central/West Pacific. They can be found in areas ranging from the Solomon Islands to Taiwan and New Caledonia, preferring environments with ample hiding places and suitable conditions for their territorial behavior.
