Etymology

akarensis: named for the Akar river system, Borneo, type locality of this species.

Distribution

Native to the island of Borneo where it has been collected in both Brunei Darussalam and parts of the Malaysian state of Sarawak with type locality 'Akar River…

Habitat

This species has been found living in clear streams with flowing water although the majority are collected from blackwater environments. It seems to be an adap…

Aquarium size

An aquarium with base dimensions of 60 ∗ 30 cm or more is recommended.

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

Temperature: 21 – 27 °C pH: 5.5 – 7.5 Hardness: 0 – 12 dGH, with lower values recommended for breeding purposes.

Preys on insects and other invertebrates in nature with very small fish perhaps being taken as well.

In the aquarium will normally accept dried foods once recognised as edible but does best when offered a varied diet.

In this case regular meals of live or frozen foods such as Daphnia, Artemia, and bloodworm will ensure the development of the best colours and condition.

Small insects such as crickets or Drosophila fruit flies are also suitable to use although it's best to fill the stomachs of these by feeding them fish flakes or some kind of vegetable matter before offering them to the fish.

Take care not to overfeed as Betta spp. seem particularly prone to obesity.

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.

Behaviour and compatibility

Not a recommended choice for the standard community set-up for reasons already touched upon. It's care requirements and disposition mean it is best kept alone …

Sexual dimorphism

Males grow larger, develop more extended fins and possess a greater amount of iridescent scaling on the head and body than females. The head profile in males i…

Reproduction

Paternal mouthbrooder. Organise a separate tank for breeding purposes unless the fish are already being maintained alone, setting this up as suggested above. T…

Notes

This species lends its name to the the Betta akarensis group of closely-related species, an assemblage which also currently includes B. antoni, B. aurigans, B.…
