{"product_id":"rusty-corydoras-osteogaster-rabauti","title":"Rusty Corydoras | Osteogaster rabauti","description":"\u003ch2\u003eDescription\u003c\/h2\u003e \u003cp\u003eThe Rusty Cory wears warm reddish-brown, rust-toned colours and the gentle, shoaling nature the genus is loved for. Reaching around 6 cm, it is a hardy, characterful bottom-dweller — always pottering the substrate in a busy little group — and a lovely, easy addition to the soft-water community aquarium.\u003c\/p\u003e \u003ch2\u003eNatural Habitat\u003c\/h2\u003e \u003cp\u003eOsteogaster rabauti (long known as Corydoras rabauti) comes from the upper Amazon in Brazil, Colombia and Peru, where it lives over soft substrates in warm, soft, slightly acidic waters among leaf litter and submerged wood. It forages in groups across the bottom for small invertebrates and organic matter.\u003c\/p\u003e \u003ch2\u003eAppearance\u003c\/h2\u003e \u003cp\u003eA classic rounded corydoras shape in warm rusty-brown to coppery tones, often with a darker band running along the back and through the body. Juveniles carry a bolder dark stripe that softens with age. Like all corys it has bony armour plating and small barbels around the mouth for sifting the substrate.\u003c\/p\u003e \u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e \u003cp\u003eThoroughly peaceful and gregarious, it should be kept in a group of at least six to feel secure and stay active. It is an ideal community bottom-dweller, mixing happily with tetras, rasboras, dwarf cichlids, gouramis and other calm fish. A soft sand or smooth, rounded-gravel substrate protects its delicate barbels.\u003c\/p\u003e \u003ch2\u003eFeeding\u003c\/h2\u003e \u003cp\u003eAn omnivore and bottom-forager. Offer good-quality sinking pellets or wafers as a staple, along with frozen and live foods such as bloodworm, daphnia and brine shrimp. It will help clean up leftover food, but should always be fed its own portion so it never goes hungry.\u003c\/p\u003e \u003ch2\u003eCare Requirements\u003c\/h2\u003e \u003cp\u003eProvide a minimum of around 90 L, with 110 L or larger better for a good group. Keep temperature at 20–27 °C, pH 5.5–7.2 and soft to moderately hard water, GH around 2–15. A soft substrate, gentle filtration, clean water and some shade or planting suit it well. A small note of caution: like other corys it can secrete a mild toxin from the pectoral spines if severely stressed, so acclimatise gently. It is plant safe.\u003c\/p\u003e \u003ch2\u003eBreeding\u003c\/h2\u003e \u003cp\u003eAn egg-depositing species. In the classic corydoras 'T-position', the female carries a few eggs in her pelvic fins and sticks them to plants, glass or décor. A cooler water change can trigger spawning. Eggs and fry receive no parental care, so a separate rearing setup improves survival.\u003c\/p\u003e \u003ch2\u003eSpecies Information\u003c\/h2\u003e \u003ctable\u003e \u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eOsteogaster rabauti (formerly Corydoras rabauti)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eRusty Corydoras, Rust Cory\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUpper Amazon (Brazil, Colombia, Peru)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003eAround 6 cm\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e5–8 years with good care\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful (schooling)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eBeginner\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e90 L\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e110 L or larger\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eOmnivore (bottom): sinking pellets, wafers, frozen and live foods\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e20–27 °C\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e5.5–7.2\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003eSoft to moderately hard, around 2–15 dGH\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003eNot applicable (freshwater)\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003ePeaceful soft-water community aquariums\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eNot applicable\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003ePlant Safe\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e \u003c\/table\u003e \u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e \u003cp\u003eSuitable tank mates include small tetras, rasboras, danios, dwarf cichlids, gouramis, other corydoras and peaceful shrimp.\u003c\/p\u003e \u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e \u003cp\u003eAvoid keeping with large or aggressive cichlids, boisterous or predatory fish, and sharp or coarse gravel that can damage the barbels.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm)","offer_id":55232799834403,"sku":"AA2058","price":19.95,"currency_code":"AUD","in_stock":true},{"title":"Medium (5-10cm)","offer_id":55232799867171,"sku":"AA2058-M","price":24.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/rusty-corydoras-osteogaster-43885220167971.webp?v=1790306097","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/rusty-corydoras-osteogaster-rabauti","provider":"Nicks AOT","version":"1.0","type":"link"}
