Origin

Schallers-mouthbrooder is an Asian betta species that originates from Indonesia and Banka where they inhabit the flood plains and small vegetated waterways.

Short description

This species is one of the rarer Betta species to be found in the aquarium trade so if you are lucky enough to get hold of some specimens they may demand higher prices. They belong to the family of Osphronemidae along with many other species from this family. Adult specimens will only reach an adult size of just under 2 inches making them ideal for the smaller aquariums but if kept in a group then allow for this with the water volume. Sadly too many Betta are kept in small containers which is cruel to the fish and a very bad practice. Their main body colouration is a grey or reddish brown main colour although the lighting in the aquarium may distort this and on the edges of their scales there will be a green tinge. They will also display a vertical dark barring on their head which runs through the eye. They are classed as a peaceful species and will do well with other tank mates of a similar size and who require the same water parameters but the males will display aggression during the spawning periods.

Lifespan

If cared for correctly Schallers-mouthbrooder should have an average lifespan of at least 3-5 years.

General care

Betta schalleri can be housed in a small aquarium if kept as as single pair, a 10 gallon tank is ideal however if you are keeping a group of these fish then you will require a larger aquarium of up to 30 gallons. A tight fitting lid will need to be used and keep the water level a couple of inches lower than the top of the aquarium. The water temperature should be set between 24 -26°C (76-79°F) and the pH should range between 4.6-5.8. These fish are quite hardy but they do require high water quality and should never be added to an immature tank setup.

Feeding

These are not a difficult fish to feed and ig healthy will have a voracious appetite. It should be remembered that they only have small mouths and stomachs so the size of the food should relate to this. Use a quality commercial flake or small pellets for the staple diet and this should be varied with treats of live or frozen foods such as brine shrimp or bloodworms.

Sexing

Mature males will have a broader head shape and develop a caudal spike on their fin. Their pelvic fins will also elongate as they mature.

Breeding

Like most of the Betta species, Schallers mouthbrooders are a paternal brooder with the male taking on all parental responsibilities. It is best to use a separate breeding tank and take care when introducing the female. If too much aggression is shown by the male split the pair and try again in 2-3 weeks. The female will mostly encourage the spawning and once the eggs have been deposited by the female and fertilised the male will scoop them up for brooding. At this stage it is advised to remove the female to prevent her getting harassed by the male. Incubation normally takes 8-10 days and when the fry are released then can be fed on newly hatched brine shrimp or Infusoria. Remove the male once the fry are free swimming and carefully perform small water changes in the fry tank on a daily basis to keep the water quality as high as possible. It is best to give the fry 3-4 small meals per day rather than a couple of larger meals.

  • Some aquarium plants absorb nutriments via leafs, so they don’t need roots actually.
  • Any fish should be kept in a tank that’s at least 5 times longer than fish’ length.
  • Green pufferfish may get along with other species, however are known to be aggressive toward own species especially if kept in small tanks.
  • External aquarium filters usually contain more space for filtration media, thus they’re more effective than internal aquarium filters.

    Live Arrival & Ordering FAQ

    Do you offer a live arrival guarantee?

    Yes. All livestock is covered by our Live Arrival Guarantee.

    In the rare event of DOA, please contact us promptly with clear photos of the livestock in the original unopened bag.

    Please review our full DOA and store policies before purchase.

    Can you ship to all states in Australia?

    No. Due to state restrictions, we cannot ship livestock or live plants to WA and TAS.

    What should I check before ordering?

    Before placing an order, make sure:

    • Your tank is fully cycled and stable
    • Your aquarium has enough space for the species
    • Your current livestock are compatible in temperament, size, and requirements
    • Your water parameters, habitat, and temperature suit the species
    • You are not adding too many fish at once
    What should I expect when my fish arrives?

    It is normal for fish, shrimp, or snails to look pale, stressed, or less active after shipping.

    This is temporary. Most livestock will settle and regain colour within a few days.

    How long does it take for fish to settle in?

    Most livestock will take 3–7 days to fully adjust to their new environment.

    Should I feed my fish immediately after arrival?

    No. We recommend waiting 24 hours before feeding to allow them to settle.

    If you already have fish in your tank, feeding them before introducing new arrivals can help reduce stress.

    Why do fish sometimes struggle after being added to a tank?

    In most cases, issues are caused by tank conditions, not shipping.

    • Uncycled or unstable tanks
    • Poor water parameters
    • Overstocking
    • Unsuitable tank mates
    What is Nano Tanks Australia’s main tip for new livestock?

    Most livestock losses happen in immature or unstable tanks, not during shipping.

    If your setup is not fully established, the risk to new arrivals is significantly higher.

    Not sure if this fish is right for your setup?

    If you are unsure whether this species suits your setup, contact us before ordering and we’ll help point you in the right direction.
