Peaceful, hardy and endlessly active, this Northern Territory native is one of the most dazzling Australian fish in the hobby. It reaches around 12–13 cm, so it wants a roomy tank where a shoal can colour up and chase.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eThis is the famous Goyder River locality form of Melanotaenia trifasciata, from the clear, plant-fringed streams and billabongs of Arnhem Land in Australia's Northern Territory. These waters run warm and clear over sand and leaf litter, with plenty of sunlight and gentle to moderate flow.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eA deep, laterally compressed rainbowfish body that grows taller and more colourful with age. The Goyder River form is prized for its blazing red-orange to fiery band running from behind the gill to the tail, over blue-green flanks. Males are larger, deeper-bodied and far more vivid than females, and colour intensifies dramatically when rival males display.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003ePeaceful and sociable, though boisterous and fast-moving. Always keep a group of six or more — a shoal settles the fish, brings out the best colour, and keeps their harmless chasing spread out. Small enough to bully tiny nano fish only by sheer energy, they suit lively community tanks.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eAn easy-going omnivore. Feed a good-quality flake or small pellet as a staple, plus regular frozen and live foods such as brine shrimp, daphnia and bloodworm to fuel colour and condition. A varied diet keeps males at their brightest.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eGive them a medium-to-large tank of at least 150 litres with open swimming space, some planting around the edges and steady flow. They are hardy and adaptable but appreciate clean, well-oxygenated water and regular water changes. Neutral to hard water suits them best, and a secure lid is wise as active rainbows can jump.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eEgg-scatterers that spawn readily among fine-leaved plants or spawning mops in the warmer months. Eggs attach by fine threads and hatch in about a week; the tiny fry need infusoria or liquid fry food before graduating to baby brine shrimp. Adults may eat eggs, so a separate spawning setup gives the best results.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eMelanotaenia trifasciata\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eGoyder River (Banded) Rainbowfish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eGoyder River, Arnhem Land, Northern Territory, Australia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003e12–13 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e5–8 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful (active, 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\u003e150 litres\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e200+ litres\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eOmnivore (flake, pellet, frozen and live foods)\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\u003e6.5–8.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003e8–25 dGH (neutral to hard)\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\u003eLarger community and native-themed 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 rainbowfish, larger tetras, peaceful barbs, danios, Corydoras, bristlenose catfish, and other robust, peaceful community fish that can keep up with their pace.\u003c\/p\u003e\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\u003cp\u003eTiny, timid nano fish that will be outcompeted at feeding time, long-finned slow fish that may be nipped, and large or aggressive cichlids.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm)","offer_id":55232828735779,"sku":"AA1519","price":23.95,"currency_code":"AUD","in_stock":false},{"title":"Medium (5-10cm)","offer_id":55232828768547,"sku":"AA1519-M","price":28.95,"currency_code":"AUD","in_stock":false},{"title":"Large (10-15cm)","offer_id":55351969939747,"sku":"AA1519-L","price":33.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/goyder-river-rainbowfish-mel-43091531694371.webp?v=1790306577","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/goyder-river-rainbowfish-melanotaenia-trifasciata-goyder-river","provider":"Nicks AOT","version":"1.0","type":"link"}
