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…

Habitat

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…

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 …

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 to offer potential nesting sites. Floating plants may be incorporated into the nest if present.

The aquarium should have the tightest-fitting cover possible (some breeders use clingfilm/plastic wrap) because the fry need access to a layer of warm, humid air without which development of the labyrinth organ can be impaired.

The pair need not be separated prior to spawning. The male might construct the nest in a tube or canister, under a broad plant leaf or among fine-leaved surface vegetation, and will not usually tolerate the female in the vicinity until it is complete.

The nuptial female becomes paler in colour and dark bars appear on the flanks. Spawning normally occurs beneath the nest in an 'embrace' typical of osphronemids, with the male wrapped around the female.

At the point of climax milt and a few eggs are released, which the female proceeds to catch between pelvic fins and body. The male then transfers these to the nest while the female recovers any loose eggs. The process is then repeated until the female is spent. This is not a particularly prolific species with less than 20 eggs being typical although bigger broods of up to 50 are not uncommon.

Post-spawning the adults can normally be left in situ, and normally both will participate in broodcare.

The eggs hatch in 24-72 hours, remaining in the nest for a further 3-4 days until the yolk sac is fully-absorbed, the male continuing to collect and return any that fall. Once the fry begin to swim freely the male will lose interest, but the adults do not usually eat their offspring.

The fry are large enough to accept motile foods such as microworm and Artemia nauplii immediately, though it should be noted that there exist reports of young Betta developing health issues if fed excessive amounts of the latter. Water changes should be small and regular rather than large and intermittent.

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.
