Overview

The Antoni betta is a small, calm mouthbrooding betta from Borneo's hill streams. It suits a keeper with a little experience.

Did you know

Before it was described, the Antoni betta moved through the hobby as Betta sp. 'Sanggau'.

Caring for the Antoni betta

A pair or a small group of Antoni bettas needs at least 16 gal (60 L). Keep the tank dim and well filtered, with gentle flow from a sponge filter. Use sand or gravel with some rock. Scatter leaf litter for cover, and fit a tight lid.

Keep the water soft and mildly acidic, at 72 to 81°F (22 to 27°C) and a pH of 5.5 to 7.0. It is an insect eater that takes dried food but does best on live and frozen daphnia, brine shrimp and bloodworm. It gets fat easily, so feed with care.

It is calm, but keep one male per tank at this size. A little squabbling with other anabantoids is normal. Choose small, peaceful tank mates only, since dwarf shrimp will be eaten.

The Antoni betta is a paternal mouthbrooder. The female usually starts the courtship. The male then broods the eggs for 12 to 17 days and can hold up to 60 fry. Breeding it is moderately difficult.

Good to know

Betta antoni is a slim fish in the Betta akarensis group of the family Osphronemidae. Tan and Ng described it in 2006 and named it for Irwan Anton, who helped the authors and gave them specimens. In life its body scales carry a blue iridescence. It has a black lower lip, a black chin bar and two black stripes behind the eye. The IUCN lists it as Endangered.

In the wild

The Antoni betta lives in clear, flowing hill streams of the Sanggau area, in the lower Kapuas basin of West Kalimantan, Borneo. It keeps to the upper reaches of the Sekayam and Melawi tributaries, in quieter margins and still pools. Those spots have leaf litter, gravel and rock under a dense canopy. The streams run very soft and only mildly acidic, at pH 5.7 to 6.3, and are sometimes faintly brown from humic acids.
