Betta Taeniata

Datasheet

General Description

Betta Taeniata, a member of the Betta picta group/complex, is a small labyrinth fish distinguished by its yellowish body and fins, and blackish head. Found primarily in Borneo, this species possesses the unique characteristic of iridescent blue scales on the male's upper body. With a maximum size of 5.5cm, it is part of the Betta genus, known for its almost 70 recognized species inhabiting various ecological niches.

Aquarium Setup

When setting up an aquarium for Betta Taeniata, a 60-litre tank without a substrate is recommended, with driftwood, roots, and branches for shelter and structure. The addition of dried leaf litter, such as beech or oak leaves, provides a natural environment and secondary food source. Dim lighting is preferred, supplemented by aquatic plant species like Microsorum pteropus and Taxiphyllum barbieri. Gentle filtration with an air-powered sponge filter and access to humid air above the water surface are crucial for this species.

Behaviour

Betta Taeniata is best kept alone or with very peaceful species due to its disposition, as larger or more vigorous fish may intimidate or outcompete it. In pair or group settings, this species exhibits intriguing behavioral interactions, although caution is advised when selecting tankmates. Small cyprinids and loaches from similar environments are compatible choices for community setups.

Feeding and Diet

In nature, Betta Taeniata feeds on insects and small invertebrates. Captive specimens readily accept dried foods but should be regularly offered live or frozen options like Daphnia, Artemia, or bloodworms to maintain optimal condition. Care must be taken to avoid overfeeding, as this species is susceptible to obesity.

Reproduction & Dimorphism

As a paternal mouthbrooder, breeding setups for Betta Taeniata should include a separate tank with a tight-fitting cover. After a courtship ritual, males embrace females to release eggs and milt. The male collects fertilized eggs in his mouth until they hatch, caring for the fry until they are free-swimming. Sexual dimorphism is evident, with males growing larger, displaying more iridescent scaling on the head, and possessing extended fins compared to females.

Habitat and Distribution

Endemic to Borneo, Betta Taeniata is commonly found in clear, flowing hill streams with a mix of leaf litter and gravel. It inhabits quiet marginal zones and still pools, sometimes in slightly brown, humid waters rich in organic material. Populations have been identified in southern Sarawak, Malaysia, and northern Kalimantan Barat, Indonesia, with collectors distinguishing localities to preserve pure bloodlines.
