[ARRIVED 16-MAY-2026] Betta Albimarginata 3-5cm (PAIR)

Description

Betta albimarginata

Rare mouthbrooding wild betta known for its striking red coloration, white fin margins, and peaceful natural behaviour

Quick Facts

  • Scientific Name: Betta albimarginata
  • Common Name: White-Edge Mouthbrooding Betta
  • Size: Approx. 4–5 cm
  • Temperament: Peaceful
  • Difficulty: 🟡 Intermediate
  • Best Kept: Pair or species group

Is this for you?

✔️ Good if:

  • You appreciate rare wild bettas
  • You enjoy natural behaviour and breeding projects
  • You keep planted or blackwater aquariums
  • You want a peaceful feature fish

❌ Avoid if:

  • You want brightly aggressive display bettas
  • You keep highly aggressive community fish
  • You prefer hard alkaline water setups
  • You want a low-attention beginner species

Why this fish?

Betta albimarginata is one of the most sought-after wild betta species due to its peaceful temperament, elegant appearance, and fascinating paternal mouthbrooding behaviour.

Males display rich red coloration with distinct white edging along the fins, creating a refined and natural appearance very different from commercial domestic bettas.

Unlike many fighting bettas, this species is generally calmer and can often be maintained successfully in carefully planned species groups or peaceful blackwater aquariums.

Care Requirements

  • Tank Size: 30L+ recommended
  • Temperature: 24–28°C
  • pH: 5.5–7.0 preferred
  • Water: Soft, clean, stable
  • Diet: Live, frozen, and quality prepared foods
  • Setup: Heavily planted with hiding spaces

Temperament & Compatibility

  • Generally peaceful for a betta species
  • Best kept with calm tank mates
  • Can be shy in busy aquariums
  • Suitable for species-focused setups
  • Avoid aggressive or fin-nipping fish

Common mistakes

  • Treating them like domestic fighting bettas
  • Keeping in overly bright or exposed tanks
  • Using hard alkaline water long-term
  • Housing with aggressive community fish
  • Skipping lid coverage — wild bettas can jump

Breeding Notes

Betta albimarginata is a paternal mouthbrooder.

After spawning, the male carries the eggs and fry in his mouth until fully developed, making this species especially interesting for hobbyists interested in natural breeding behaviour.

Stable soft water and low-stress conditions significantly improve breeding success.

Pair with

  • Leaf litter and driftwood
  • Blackwater botanicals
  • Soft lighting and floating plants
  • Live and frozen foods
  • Peaceful nano fish

Important Notes

  • This is a wild betta species, not a domestic splendens type
  • Colours may intensify with maturity and conditioning
  • Requires stable water quality
  • Secure lid recommended
  • Best suited to calm aquariums
NTA Insight:
Wild bettas like albimarginata are often less about flashy finnage and more about behaviour, rarity, and natural interaction. Many hobbyists end up preferring them over domestic bettas once they experience their calmer temperament and breeding behaviour.

    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.
