{"product_id":"hengeli-rasbora-trigonostigma-hengeli","title":"Hengeli Rasbora | Trigonostigma hengeli","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eHengel's Rasbora is the daintiest of the harlequin trio — a glassy, slender little fish lit by a glowing copper-orange \"candle flame\" above its slim black mark. Peaceful and quietly beautiful, it comes into its own in a big shoal in a soft, shaded planted tank, staying tiny at around 3 cm.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eTrigonostigma hengeli comes from the peat swamp forests and blackwater streams of Sumatra and Borneo in Indonesia. These are soft, acidic, tannin-stained waters, dimly lit beneath the forest canopy and rich in leaf litter.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eA small, semi-transparent rasbora with a narrow black wedge on the rear body, topped by a bright, glowing patch of orange-copper that resembles a candle flame. It is more slender and see-through than the harlequin, and the orange \"flame\" is most vivid in settled, well-conditioned males.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003eCompletely peaceful and rather shy. Keep a shoal of at least 10–12 for confident behaviour and the best colour; in small numbers they hide and lose condition. Ideal for gentle nano and blackwater communities.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eA micro-omnivore with a tiny mouth. Feed small, high-quality flake and micro-pellets along with baby brine shrimp, micro-worm and daphnia. Frequent small feeds suit them best.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eAn aquarium of 45 litres or more suits a good shoal. Hengel's rasbora is at its best in soft, acidic, gently filtered water with planting, subdued lighting and some botanicals or tannins to recreate its blackwater home. Stable, clean conditions and regular water changes keep it healthy.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eLike its relatives it is a plant-spawner, depositing eggs on the underside of broad leaves in soft, acidic, warm water. Adults will eat the eggs, so a separate, dimly lit, densely planted breeding tank gives the best chance, and the tiny fry need infusoria-grade first foods.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eTrigonostigma hengeli\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eHengel's Rasbora (Glowlight Rasbora)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eSumatra and Borneo, Indonesia, South-East Asia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003e3–3.5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e3–5 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful (schooling)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eBeginner–Intermediate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e45 litres\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e60+ litres\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eMicro-omnivore (small flake, micro-pellet, tiny live\/frozen foods)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e23–28 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e5.5–7.0 (soft, acidic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003e1–8 dGH (soft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003eNot applicable (freshwater)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003eSoft-water nano, planted and blackwater aquariums\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eNot applicable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlant Safe\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\u003cp\u003eOther small, peaceful soft-water fish — small tetras, other rasboras, pygmy Corydoras, Otocinclus, dwarf gouramis and peaceful dwarf cichlids.
