Hengeli Rasbora

Description

Scientific Name Trigonostigma Hengeli
Family Cyprinidae
pH 5.5 – 7.5
DH 1 – 14
Temp 22 – 28 degrees
Life Span 3 – 5 years

Origin
Sumatra & Borneo Islands in Indonesia. They reside in blackwaters and slower flowing streams.

Description
The Hengeli Rasbora is also called the Growlight Rasbora. Being the smallest of the trigonostigma genus the Hengeli will grow up to 3 – 4cm in length. Most of their body is translucent with the most significant feature, a bright orange marking on the lateral line from the centre of its body to the Caudal fin with a black marking underneath this. Males are not as round as females. Although this species of Rasbora is quite hardy it is not recommended to use this fish while cycling a new aquarium.

Environment
Provide a tank that is dimly lit with lots of plants for hiding spaces as the Hengeli is a shy fish. Keep filter flow to a minimum, allowing wide open spaces for them to swim around in as they are quite energetic. A darker substrate will help to bring out the Rasbora’s colours. They can tolerate a wide range of conditions. Maintain pH from 5.5 – 7.5 and soft to moderately hard water 1 – 12 dGH. Minimum tank size for a group should be at least 100 litres.

Behaviour
The Hengeli Rasbora is extremely peaceful and suitable for any aquarium with non-aggressive fish. The more placid the better. It’s a shoaling fish and best kept in a group of at least 6 or more as this makes them feel more relaxed about their environment. The more the better when it comes to shoaling fish. A hierarchy will be formed within the group. The main area of the tank it likes to reside in is the middle, but it will frequent the top and bottom as well. This species of Rasbora is a faster swimmer than other Rasbora.

Food
The Hengeli Rasbora is an omnivore so it will enjoy a wide range of foods as it is not too fussy. Flake food, worms, live and frozen food like brine shrimp, daphnia, mosquito larvae & vegetables. Keep serving sizes small as they are not big fish.

Disease
There are no specific diseases that directly affect this species but they are prone to a variety of others.

Breeding
Although very difficult to breed in an aquarium it can be achieved. Keep water conditions optimal, providing them with soft acidic conditions. They will attach their eggs to the undersides of leaves. To induce spawning keep the tank quite dark, feed lots of live foods and even do water changes to simulate a change of seasons. So the parents do not eat their young, they should be removed after spawning. Feed young infusorians to begin, moving onto brine shrimp and then powdered fry foods as they get bigger.

    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.
