Betta Enisae

Datasheet

General Description

In the Betta Enisae species, the males grow larger and possess a greater amount of iridescent scaling on the head, a broader head shape, and more extended fins than the females. The fish in this species are grouped within the B. pugnax complex, sharing similar characteristics such as a relatively large head, brown coloration with iridescent spots, and an anal fin that is pointed and elongated in mature specimens. They are known for their unique features like the presence of transverse bars in the caudal fin and a specific lateral scale count.

Aquarium Setup

The Betta Enisae can be maintained in a fully-decorated aquarium without substrate for ease of maintenance. Driftwood, roots, and branches can be included to create shady spots. Dried leaf litter like beech, oak, or Ketapang almond leaves can be added to enhance a natural feel, provide cover, and foster microbe colonies. Dim lighting and aquatic plants that thrive under such conditions, along with floating vegetation, can be beneficial. Filtration should be gentle, such as an air-powered sponge filter, to avoid strong currents. Additionally, the tank should be well-covered but not filled to the top to allow access to a layer of humid air for the fish.

Behaviour

Due to the specific requirements and disposition of Betta Enisae, it is best kept alone or with very peaceful species. Larger or more vigorous fish can intimidate and outcompete them. However, they can coexist with small cyprinids and loaches that share similar natural environments. These fish can be kept in pairs or groups, displaying intriguing behavioral interactions under the latter circumstance.

Feeding and Diet

In the wild, Betta Enisae likely preys on insects and small invertebrates or zooplankton. Captive individuals readily accept dried foods once they recognize them as edible. However, offering live or frozen foods like Daphnia, Artemia, or bloodworm regularly is recommended to maintain optimal color and condition. Care should be taken not to overfeed, as Betta species are prone to obesity.

Reproduction & Dimorphism

Betta Enisae is a paternal mouthbrooder. Breeding requires a separate tank with a tight-fitting cover to maintain warm, humid air for fry development. The breeding process involves a courtship ritual, egg and milt release, and parental care after fry hatching. Males exhibit larger size, more iridescence, and elongated fins compared to females.

Habitat and Distribution

Found in the River Kapuas basin in Indonesia, Betta Enisae inhabits cool, flowing streams in forest swamps with shaded, low-light environments. These waters are stained with humic acids, low in dissolved minerals, and filled with fallen leaves and tree roots. Populations from various locations show differences in coloration and patterns, emphasizing the importance of accurate labeling and preservation of distinct bloodlines.
