Danilanio: The New Frontier in Freshwater Aquariums

Danio axelrodi, commonly referred to as danio, is a small freshwater fish belonging to the Cyprinidae family and is a popular choice for home aquariums due to its hardiness, vibrant coloration, and active behavior. Recently, a new species of danio has emerged, known as Danilanio frankei, which has attracted considerable attention among aquarium enthusiasts. This article delves into the remarkable characteristics of Danilanio frankei and explores its potential in the freshwater aquarium hobby.

Discovering Danilanio frankei

Danilanio frankei was first discovered in 2006 in the Tanintharyi River basin in Myanmar (formerly Burma). It is a relatively small fish, with males reaching a maximum length of approximately 2.5 cm (1 inch) and females slightly larger, reaching up to 3 cm (1.2 inches). Danilanio frankei exhibits a striking coloration, with males displaying a vibrant blue-green body adorned with a prominent black stripe running along its lateral line. In contrast, females typically display a more subdued olive-green coloration with a less defined black stripe.

Behavioral Traits of Danilanio frankei

Danilanio frankei is a highly active and social fish, preferring to live in groups of at least 6-8 individuals. They are known for their peaceful and non-aggressive nature, making them compatible with a wide range of other peaceful species, including neon tetras, rasboras, andCorydoras catfish.

In terms of their swimming behavior, Danilanio frankei exhibits a unique and captivating pattern. They are often seen swimming in tight-knit groups, darting around the aquarium with incredible speed and agility. This behavior adds a sense of dynamism and excitement to the aquarium environment.

Habitat Requirements for Danilanio frankei

To provide Danilanio frankei with an optimal living environment, it is crucial to recreate their natural habitat as closely as possible. They prefer well-oxygenated water with a temperature range between 22-26°C (72-79°F) and a pH level between 6.5-7.5.

The aquarium should be densely planted with live vegetation, providing plenty of hiding places and areas for exploration. Danilanio frankei is also known to appreciate a gentle current in the aquarium, which can be achieved using a small water pump or filter.

Diet and Feeding Habits of Danilanio frankei

Danilanio frankei is a micropredator, primarily feeding on small invertebrates in the wild. In captivity, they can be fed a varied diet consisting of live foods such as brine shrimp, daphnia, and microworms. Frozen or freeze-dried foods, including bloodworms and mysis shrimp, are also readily accepted. It is important to offer a variety of foods to ensure a balanced diet that meets their nutritional needs.

Breeding and Reproduction in Danilanio frankei

Breeding Danilanio frankei is relatively easy, providing the appropriate conditions are met. A separate breeding tank is recommended, with water parameters similar to those of the main aquarium. The tank should be well-planted with fine-leaved plants, such as Java moss or hairgrass, to provide spawning sites for the eggs.

Conditioning the breeding pair with live foods a few weeks before spawning is essential to increase the chances of successful reproduction. The spawning process typically occurs in the morning, with the female scattering numerous adhesive eggs among the plants. The eggs hatch within approximately 24-48 hours, and the fry are free-swimming within 3-4 days.
