General Description
Betta burdigala is an incredibly rare species within the aquarium trade, often misidentified as B. uberis or other congeners due to its inclusion in the Betta coccina group. These fishes are typically small, reaching sizes of up to 40 mm SL, with red or black body colouration and possessing 9 abdominal vertebrae, distinguishing them from other Betta species. They are stenotypic inhabitants of forest peat swamps.
Aquarium Setup
When setting up an aquarium for Betta burdigala, it is crucial to maintain a fully-decorated tank with driftwood, roots, branches, and dried leaf litter to mimic their natural habitat. Aquatic plant species like Microsorum, Taxiphyllum, or Cryptocoryne spp. can be added, alongside floating vegetation. Soft water with acidic conditions and minimal carbonate hardness is essential, achieved through methods like a reverse osmosis unit. A gentle air-powered sponge filter and a partially covered tank to allow access to the layer of humid air above the water surface are also recommended.
Behaviour
Not recommended for standard community setups, Betta burdigala can be housed with small cyprinids and loaches in suitable conditions. There are mixed reports about maintaining them in pairs or harem-like groups, with observations of occasional chasing and squabbling over territory. In some cases, sustained aggression towards conspecifics has been noted, suggesting that single pairs may be preferable.
Feeding and Diet
In the wild, Betta burdigala likely preys on insects and small invertebrates, while captive individuals readily accept dried foods but should be supplemented with live or frozen options like Daphnia, Artemia, or bloodworms. Care should be taken to prevent overfeeding, as these fish are prone to obesity.
Reproduction & Dimorphism
Betta burdigala is a bubble-nester, with males being more colorful and developing longer fins as they mature. Adequate cover and nesting sites should be provided for successful breeding, with the male responsible for building and guarding the nest. Post-spawning, the male cares for the eggs and fry until they are independent.
Habitat and Distribution
Endemic to the island of Bangka, Indonesia, Betta burdigala inhabits peat swamps and blackwater streams with low pH and negligible dissolved mineral content. The fish navigate through the dark, leaf-covered waters, surviving within moist leaf litter during periods of limited access to permanent water sources.
