It is weakly electric, using this ability to navigate and locate food in low light, making it a genuinely unique fish to observe after dark.\u003c\/p\u003e\n\u003cp\u003eThis is a large-growing species that can reach 45-50 cm, so a spacious aquarium is required to accommodate its adult size long-term. It's a nocturnal, predatory feeder toward very small fish, so tankmates should be similarly sized or larger, with caves or pipes provided for daytime hiding.\u003c\/p\u003e\n\u003cp\u003eAt N8 Aquatics, our fish are carefully raised and conditioned to ensure healthy stock suited to home aquariums.\u003c\/p\u003e\n\u003ch3 style=\"color: #2d5f3f; margin-top: 20px;\"\u003eSpecies Snapshot\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize Sold:\u003c\/strong\u003e Juvenile, 8-12 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdult Size:\u003c\/strong\u003e 45-50 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank Size:\u003c\/strong\u003e 200 L minimum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperament:\u003c\/strong\u003e Peaceful but predatory towards very small fish, nocturnal, weakly electric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature:\u003c\/strong\u003e 25-28°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epH:\u003c\/strong\u003e 6.0-7.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDifficulty:\u003c\/strong\u003e Moderate (sensitive to poor water quality and some medications)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #2d5f3f; margin-top: 20px;\"\u003eIdeal Habitat and Care\u003c\/h3\u003e\n\u003cp\u003eProvide caves or pipes for daytime hiding, dim lighting, and a spacious tank that accommodates this species' large adult size and nocturnal habits.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature:\u003c\/strong\u003e 25-28°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epH:\u003c\/strong\u003e 6.0-7.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Flow:\u003c\/strong\u003e Moderate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance:\u003c\/strong\u003e Frequent, consistent water changes to maintain water quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #2d5f3f; margin-top: 20px;\"\u003eDiet\u003c\/h3\u003e\n\u003cp\u003eA carnivorous diet supports this predatory species' growth and health.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSinking pellets as a staple\u003c\/li\u003e\n\u003cli\u003eFrozen bloodworm, brine shrimp and mysis\u003c\/li\u003e\n\u003cli\u003eLive food appreciated occasionally\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #2d5f3f; margin-top: 20px;\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eCalm and predatory only toward very small fish, this species suits tankmates that are similarly sized or larger and won't fit in its mouth.\u003c\/p\u003e\n\u003cp\u003eSuitable tankmates include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCalm, similarly sized or larger community fish\u003c\/li\u003e\n\u003cli\u003eLarger barbs and gourami\u003c\/li\u003e\n\u003cli\u003eRobust, non-nipping species\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAvoid aggressive or fin-nipping species.\u003c\/p\u003e\n\u003ch3 style=\"color: #2d5f3f; margin-top: 20px;\"\u003eWhy Buy From N8 Aquatics\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCarefully raised aquarium fish\u003c\/li\u003e\n\u003cli\u003eHealthy, well-conditioned stock\u003c\/li\u003e\n\u003cli\u003eStrong genetics and vibrant colouration\u003c\/li\u003e\n\u003cli\u003eBreeder support if you have questions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #2d5f3f; margin-top: 20px;\"\u003ePickup Information\u003c\/h3\u003e\n\u003cp\u003eN8 Aquatics currently operates as a local pickup-only breeder in Central Queensland.\u003c\/p\u003e\n\u003cp\u003eOrders are collected by appointment after purchase confirmation.\u003c\/p\u003e\n\u003cp\u003ePlease ensure you are able to collect your fish before placing an order.\u003c\/p\u003e\n\u003ch3 style=\"color: #2d5f3f; margin-top: 20px;\"\u003eImportant\u003c\/h3\u003e\n\u003cp\u003eAll livestock sold by N8 Aquatics should be introduced to fully cycled aquariums suitable for the species being kept.\u003c\/p\u003e\n\u003cp\u003ePlease ensure your aquarium setup and tankmates are appropriate before purchasing.\u003c\/p\u003e","brand":"N8 Aquatics","offers":[{"title":"5cm","offer_id":47863557259369,"sku":"PISCES-25000","price":22.95,"currency_code":"AUD","in_stock":false},{"title":"7cm","offer_id":47863557292137,"sku":"PISCES-25012","price":28.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/9520\/1897\/files\/7cm_Black_Ghost_Knife_Fish_ebb3e6ea-e265-4797-8737-94f3b89b93b6.jpg?v=1785898026","url":"https:\/\/n8aquatics.com\/products\/black-ghost-knife-fish","provider":"N8 Aquatics","version":"1.0","type":"link"}
