Etymology

Betta: from ikan betah, the vernacular Malay for species of this genus. miniopinna: from the Latin minius, meaning 'cinnabar-red', and pinna, meaning 'fin', in…

Distribution

Endemic to Bintan Island, Riau Islands province, Indonesia, where it is known only from a handful of localities in the northern portion of the island. Type loc…

A stenotopic inhabitant of peat swamp forests and associated streams. The dense canopy of branches above means very little light penetrates the surface of such environments, although they are increasingly disturbed by human activity.

The water is typically stained darkly with humic acids and other chemicals released by decaying organic material. The dissolved mineral content tends to be negligible and pH can be as low as 3.0 or 4.0.

The substrate is usually covered by fallen leaves, branches and submerged tree roots and at certain times of year the fish may be forced to survive within the moist leaf litter for several weeks since permanent water is not always available.

During a trip to Bintan Island in August 2013, <i>B. miniopinna</i> was collected from a pocket of degraded peat swamp forest where much of the vegetation appeared to be dying back and a large inundated open area had formed due to construction of a road (see images). The fish were collected only from black water puddles beneath relatively pristine canopy, and the congener B. spilotogena was found at the same location.

Bintan has been developed for tourism over the last decades and is heavily-promoted by Indonesia, with luxury beach resorts and golf courses increasing in number. Further deforestation has occurred in order to establish large rubber plantations in the interior of the island. B. miniopinna is now restricted to a few remaining pockets of primary peat swamp forest and has been listed as 'Critically Endangered' on the IUCN Red List of Threatened Species since 1996.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the pageFor example, the Behaviour and compatibility section already says this.

Anything worth adding

Describe what you saw, or which part of the source says this.

Aquarium size

An aquarium with base measurements of 45 ∗ 30 cm should be the minimum considered, but is suitable for a pair or small group.

Maintenance

Can be maintained in a fully-decorated aquarium although many breeders prefer not to use a substrate for ease of maintenance. Driftwood roots and branches can …

Water conditions

Diet

Likely to prey on small aquatic and terrestrial invertebrates in nature. Captive fish will normally accept dried products once they are recognised as edible, b…

Behaviour and compatibility

Not recommended for the standard community aquarium. Its care requirements and disposition mean it is best kept alone or with very peaceful species. Some small…

Sexual dimorphism

Males are more intensely-coloured and develop more-extended fins than females as they mature.

Reproduction

Bubble nester. It is particularly important to provide plenty of cover for the female, and empty camera film canisters or lengths of plastic tubing can be used…

Notes

This species is included in the B. coccina group of closely-related species within the genus. This assemblage mostly comprises small, red-coloured fishes with …
