Unlike some of the more intensely colored rainbowfish, this species displays a subtle blend of silvery-blue tones with warm golden or amber highlights, often accented by a gentle sheen that shifts in the light. When settled and in good condition, males in particular will develop richer color and a slightly deeper body, especially during displays.\u003c\/p\u003e\n\u003cp data-start=\"552\" data-end=\"1008\"\u003ePeaceful and constantly on the move, Omba Rainbowfish thrive in groups and bring a calm, natural energy to the aquarium. They are best kept in schools of at least 6, where their social dynamics and occasional sparring displays between males can be observed. Despite their activity, they are non-aggressive and mix well with other similarly sized, peaceful species. A longer tank is ideal to accommodate their steady swimming and encourage natural behavior.\u003c\/p\u003e\n\u003cp data-start=\"1010\" data-end=\"1386\"\u003eA planted aquarium with open swimming space suits them best, along with clean, well-maintained water. They appreciate stable conditions and benefit from regular water changes to maintain their health and coloration. Feeding a varied diet will help bring out their best—high-quality flakes or micro pellets paired with frozen or live foods will enhance both color and vitality.\u003c\/p\u003e\n\u003cp data-start=\"1388\" data-end=\"1411\"\u003e\u003cstrong data-start=\"1388\" data-end=\"1409\"\u003eCare Information:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1412\" data-end=\"1832\"\u003e\n\u003cli data-section-id=\"1o90x4d\" data-start=\"1412\" data-end=\"1479\"\u003e\n\u003cstrong data-start=\"1414\" data-end=\"1428\"\u003eTank Size:\u003c\/strong\u003e Minimum 30 gallons (larger for proper schooling)\u003c\/li\u003e\n\u003cli data-section-id=\"1sf2n5k\" data-start=\"1480\" data-end=\"1518\"\u003e\n\u003cstrong data-start=\"1482\" data-end=\"1498\"\u003eTemperature:\u003c\/strong\u003e 74–82°F (23–28°C)\u003c\/li\u003e\n\u003cli data-section-id=\"p9p92w\" data-start=\"1519\" data-end=\"1538\"\u003e\n\u003cstrong data-start=\"1521\" data-end=\"1528\"\u003epH:\u003c\/strong\u003e 6.5–7.5\u003c\/li\u003e\n\u003cli data-section-id=\"1ypze1n\" data-start=\"1539\" data-end=\"1584\"\u003e\n\u003cstrong data-start=\"1541\" data-end=\"1557\"\u003eTemperament:\u003c\/strong\u003e Peaceful, schooling fish\u003c\/li\u003e\n\u003cli data-section-id=\"113p4eb\" data-start=\"1585\" data-end=\"1626\"\u003e\n\u003cstrong data-start=\"1587\" data-end=\"1602\"\u003eGroup Size:\u003c\/strong\u003e 6 or more recommended\u003c\/li\u003e\n\u003cli data-section-id=\"ji8z78\" data-start=\"1627\" data-end=\"1702\"\u003e\n\u003cstrong data-start=\"1629\" data-end=\"1644\"\u003eTank Setup:\u003c\/strong\u003e Planted tank with open swimming areas and moderate flow\u003c\/li\u003e\n\u003cli data-section-id=\"1fmkuhq\" data-start=\"1703\" data-end=\"1787\"\u003e\n\u003cstrong data-start=\"1705\" data-end=\"1714\"\u003eDiet:\u003c\/strong\u003e High-quality flakes or pellets, supplemented with frozen or live foods\u003c\/li\u003e\n\u003cli data-section-id=\"z9zvig\" data-start=\"1788\" data-end=\"1832\"\u003e\n\u003cstrong data-start=\"1790\" data-end=\"1803\"\u003eLifespan:\u003c\/strong\u003e 5–7 years with proper care\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1834\" data-end=\"2007\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\u003cstrong data-start=\"1834\" data-end=\"1846\"\u003eSummary:\u003c\/strong\u003e A peaceful and elegant schooling rainbowfish with subtle, shifting coloration—ideal for planted community tanks where its natural beauty and behavior can shine.\u003c\/p\u003e","brand":"Poseidon Aquatics And Plants","offers":[{"title":"Default Title","offer_id":48133054824670,"sku":null,"price":24.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/4768\/4574\/files\/Photo_c76bf674-ca83-49a4-aa92-26174c534b16.png?v=1741201181","url":"https:\/\/poseidonaquaticsandplants.com\/products\/omba-rainbowfish-melanotaenia-dumasi","provider":"Poseidon Aquatics And Plants","version":"1.0","type":"link"}
