Aquarium Setup

Creating a suitable environment for the Flame Cardinalfish is vital for their well-being.

• Tank Size: A minimum tank size of 30 gallons is recommended to accommodate their schooling nature and active behavior.
• Aquascaping: Mimicking their natural habitat with rock formations and plenty of hiding spots will help them feel secure. Use live rock to enhance biological filtration and offer crevices for exploration.

Water Parameters

Ensuring optimal water conditions is crucial for maintaining healthy Flame Cardinalfish.

Parameter	Ideal Range
pH Level	8.1-8.4
Temperature	22-27°C (72-81°F)
Salinity	1.020-1.025 sg
Nitrite & Ammonia	0 ppm
Nitrate	< 20 ppm

Compatibility with Tankmates

Selecting suitable tankmates is essential to maintaining harmony in an aquarium housing Flame Cardinalfish.

• Peaceful Co-inhabitants: Opt for other peaceful species, such as gobies, blennies, and non-aggressive damselfish, which share similar environmental preferences.
• Avoid Aggressive Species: Steer clear of highly territorial or aggressive fish, which could stress or outcompete the Flame Cardinalfish for resources.

Lesser-Known Facts About the Flame Cardinalfish

Beyond its beauty and behavior, the Flame Cardinalfish has some unique features that are less commonly known:

• Bioluminescent Adaptations: Some studies suggest that like other Apogon species, Flame Cardinalfish may possess bioluminescent properties, although this is not visually apparent.
• Role in Ecosystem: They play a pivotal role in the marine food web, both as predators of small zooplankton and prey for larger fish.
• Reproduction: Flame Cardinalfish exhibit mouthbrooding behavior, where the male carries fertilized eggs in his mouth for protection until they hatch, an intriguing reproductive strategy that enhances survival rates in challenging environments.
