General Description
The Purple Firefish, also known as Nemateleotris decora, belongs to the Microdesmidae family and is characterized by its torpedo-like shape. It is native to the Indo-Pacific region, ranging from Mauritius to Samoa and as far north as the Ryukyu Islands and south to New Caledonia.

Aquarium Suitability
The Purple Firefish is considered suitable for aquariums with care. They are known to be docile but may display aggression towards similar species. These fish are hardy and can thrive in a tank with a minimum size of 90 liters. When keeping them in an aquarium, it is important to provide hiding places as they are very shy and require spaces to retreat to, especially when newly introduced.
Care and Hardiness
Purple Firefish are hardy fish that can adapt well to aquarium conditions. They are peaceful but can be threatened by larger, more aggressive tank mates. To ensure their well-being, it is recommended to keep them with smaller, peaceful fish to prevent competition for food. Additionally, dimming the lights when first introducing them to the tank can help them acclimate better.
Reef Suitability
The Purple Firefish is always reef safe, making it a suitable addition to reef aquariums. They are known to coexist peacefully with coral and other reef inhabitants without causing any harm to the delicate ecosystem.
Aquarium Setup
When setting up an aquarium for Purple Firefish, it is essential to include hiding spots such as rocks or caves where they can retreat when needed. Maintaining stable water conditions with a temperature range of 22.2-25.6°C, pH levels between 8.1-8.4, a specific gravity of 1.020-1.025, and a carbonate hardness of 8-12 dKH is crucial for their well-being.
Behaviour
Purple Firefish are generally docile but can exhibit aggression towards similar species. They prefer to live in pairs consisting of a male and a female. These fish are known to be shy and will seek shelter when feeling threatened.
Feeding and Diet
The diet of Purple Firefish consists of small crustaceans such as krill, mysis, and artemia, as well as zooplankton like cyclops and pods. Ensuring that their food is enriched with essential vitamins is crucial to maintaining their vibrant coloration and overall health.
Dimorphism
In captivity, Purple Firefish can live as a pair, with male and female counterparts often forming a bond. Their reproductive behavior in aquarium settings can vary, but successful captive reproduction has been reported when specific conditions are met.
Habitat and Distribution
Purple Firefish are commonly found in the East Indian Ocean, West Indian Ocean, Australia, the Red Sea, and Indonesia. They inhabit rocky reefs and areas with ample hiding places to seek refuge when necessary. Their vibrant purple coloration makes them a sought-after species in both the wild and in aquariums.
