{"product_id":"glowlight-tetra-hemigrammus-erythrozonus","title":"Glowlight Tetra | Hemigrammus erythrozonus","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThe Glowlight Tetra draws a single glowing red-gold line down a glassy body — subtle, elegant and thoroughly peaceful. Reaching around 4–5 cm, it is a lovely, hardy shoaler that looks its best in a group in soft, gently-lit water, especially over a dark substrate.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eNative to the Essequibo river drainage of Guyana in South America, in soft, acidic blackwater streams stained with tannins. It lives in shaded, slow-moving water among leaf litter and submerged roots, schooling in the middle layers.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eA slender, translucent silver-bronze body crossed from snout to tail by a single iridescent red-gold stripe that appears to glow under gentle light. The leading edge of the dorsal fin echoes the same red. Colour is richest over dark substrate in soft water.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003ePeaceful, gentle and social — always kept in a group of six or more. It is an ideal community fish that mixes well with other small, calm species and will not bother anything.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eAn omnivore that takes small foods eagerly. Feed a quality micro-pellet or flake as the staple, with frozen or live daphnia, brine shrimp and small bloodworm to bring out colour and condition.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eHardy and beginner-friendly once established, though it shows best in soft, slightly acidic water with subdued lighting, planting and some tannin-stained cover. Provide clean, stable water and a group for a relaxed, colourful display.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eAn egg-scatterer that spawns among fine-leaved plants in soft, acidic water. Adults will eat the eggs, so a separate spawning setup with a mesh or dense moss gives the best results; fry are tiny and 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\u003eHemigrammus erythrozonus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eGlowlight Tetra\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eEssequibo drainage, Guyana, South America\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003e4–5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e4–5 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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e60 litres\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e75+ litres\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eOmnivore (micro)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e24–28 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e6.0–7.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003e2–12 dGH\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 planted community 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 tetras and rasboras, dwarf gouramis, honey gouramis, Corydoras, pencilfish, small rasboras and peaceful dwarf cichlids such as rams.\u003c\/p\u003e\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\u003cp\u003eLarge or aggressive fish, boisterous barbs and fin-nippers, and anything big enough to view a 4 cm tetra as a meal.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm)","offer_id":55232817037603,"sku":"AA1534","price":6.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/Glowlight_Tetra.jpg?v=1781483461","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/glowlight-tetra-hemigrammus-erythrozonus","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
