Threadfin Rainbowfish Iriatherina werneri
Care Guide:
The Threadfin Rainbowfish (Iriatherina werneri) is a truly stunning and elegant freshwater fish. Notably, this peaceful species comes from the slow-moving, heavily planted swamps of northern Australia and New Guinea. It stands out because of its incredibly long, thread-like fin rays and beautiful pastel body colours. Consequently, it represents a premier choice for dedicated nano aquarium enthusiasts.
Max Size and Shoaling Behaviour
In the home aquarium, these tiny fish grow to a maximum adult length of roughly 4 to 5 centimetres. Because they are exceptionally peaceful but naturally timid, they must never be housed with large or aggressive tankmates. Furthermore, they are highly social, dedicated shoaling animals that draw confidence from numbers. Therefore, you must always keep them in groups of six to eight specimens to ensure they feel secure.
Ideal Water Parameters
Keeping the water clean is highly beneficial for their long-term health, as they have zero tolerance for sudden chemical drops. Because they come from slow-moving wild environments, they prefer gentle filtration over heavy currents. The ideal parameters include:
-
- Acidity Range: A stable pH maintained between 6.0 and 7.5.
- Temperature Range: Kept consistently warm between 23°C and 28°C.
- Water Hardness: Soft to moderately hard conditions (5–15 dGH).
- Filtration: A gentle sponge filter or slow-flow hang-on-back filter.
Structural Layout and Live Plants
Furthermore, the physical setup of the tank must cater directly to their love of dense cover. Incorporating plenty of fine-leaved live plants and floating vegetation is highly recommended to provide safety. Additionally, a tightly fitted lid is mandatory because these sleek fish are highly agile jumpers. If you use dark sand or a rich aquasoil base, their delicate fin colours will look far more intense.
Dietary Habits and Nutrition
When considering food, they are specialized micro-predators with incredibly small throats. Although they may eventually accept tiny crushed flakes, offering small live or frozen items is essential to maintain their vibrant health. Specifically, to encourage their best natural condition and magnificent fin displays, their daily feeding routine should include:
-
- Nutritious live or frozen baby brine shrimp (Artemia nauplii).
- High-protein live or frozen copepods, rotifers, and small daphnia.
- Finely powdered micro granules designed for tiny surface feeders.
Peaceful Coexistence and Tankmates
Finally, these delightful creatures have an exceptionally peaceful nature, making them ideal community residents for specialized nano tanks. While males will happily explore open spaces to display their fins to rivals, they never harm their neighbors. However, you should completely avoid housing them with fin-nippers like Tiger Barbs. Consequently, good choices for companions include ornamental dwarf shrimp, small snails, and peaceful neon tetras.
