Iriatherina werneri "Threadfin Rainbowfish"
The Threadfin Rainbowfish (Iriatherina werneri) is a small and colorful species of freshwater fish that belongs to the Melanotaeniidae family. Here are some key features and information about Iriatherina werneri:
Appearance: Threadfin Rainbowfish are known for their delicate appearance and distinctive thread-like extensions on their fins. The males usually have longer and more elaborate extensions, especially on the dorsal fin. The body coloration can range from silver to blue with iridescent hues.
Size: Adult Threadfin Rainbowfish typically reaches a size of about 1.5 to 2 inches (3.8 to 5 centimeters).
Habitat: This species is native to Northern Australia, including Queensland and the Northern Territory. They inhabit slow-moving streams, ponds, and swamps with dense vegetation.
Behavior: Threadfin Rainbowfish are peaceful and social. They are schooling fish, and keeping them in groups is recommended to provide a more natural and secure environment. The males may display colorful courtship behaviors.
Diet: In the aquarium, Threadfin Rainbowfish are generally omnivorous. They will accept high-quality flake or micro-pellet food. Live or frozen foods such as daphnia, brine shrimp, and small insects can be included in their diet.
Tank Requirements: Provide a well-planted aquarium with open swimming spaces. They prefer slightly acidic to neutral water conditions with a temperature range of 73-81°F (23-27°C). Regular water changes and good filtration are important.
Compatibility: Threadfin Rainbowfish is peaceful and can be kept with other small, non-aggressive fish species. They are suitable for community aquariums with species that share similar water requirements.
Breeding: Breeding Threadfin Rainbowfish can be challenging due to their delicate nature. Provide a well-maintained aquarium with fine-leaved plants for egg deposition. The eggs are adhesive and will attach to surfaces. Providing a separate breeding tank or a spawning mop can help increase the chances of fry survival.
Threadfin Rainbowfish are appreciated for their unique fin extensions and lively behavior. Proper care, a suitable environment, and a well-balanced diet contribute to their overall well-being in the aquarium
