It navigates using a weak electric field. Native to rivers across much of South America, it suits experienced keepers with a large, dim, well-filtered aquarium.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eAdult Size:\u003c\/em\u003e Around 35–50 cm (14–20 in); up to 50 cm in large tanks\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLifespan:\u003c\/em\u003e 10–15 years\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eOrigin\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eNative to:\u003c\/em\u003e Amazon, Orinoco, Paraguay and Paraná basins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eHabitat:\u003c\/em\u003e Sandy-bottomed creeks and rivers, sheltering by day\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eFeeding\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eDiet:\u003c\/em\u003e Carnivorous\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePreferred Foods:\u003c\/em\u003e Bloodworm, brine shrimp, earthworms, prawns, mussel, sinking carnivore pellets\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFeeding Habits:\u003c\/em\u003e Feed at dusk or after lights out; daily for juveniles, adults 4–5 times weekly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eTank Mates\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBest with:\u003c\/em\u003e Peaceful medium-sized fish: larger tetras, Geophagus, Corydoras, plecos, angelfish\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eAvoid:\u003c\/em\u003e Small fish and shrimp it can swallow; fin-nippers; other knifefish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eAggression \u0026amp; Behaviour\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eTemperament:\u003c\/em\u003e Shy and peaceful with anything too big to eat\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eTerritoriality:\u003c\/em\u003e Territorial towards its own kind and other electric fish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eExperience Level\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eDifficulty:\u003c\/em\u003e Intermediate to Advanced\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eChallenges:\u003c\/em\u003e Sensitive to poor water and medications; nocturnal; needs space\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eWater Parameters\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eWater Type:\u003c\/em\u003e Freshwater, soft to moderately hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eTemperature:\u003c\/em\u003e 23–28°C (73–82°F)\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003epH:\u003c\/em\u003e 6.0–7.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eHardness:\u003c\/em\u003e 5–15 dGH\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFlow:\u003c\/em\u003e Moderate, well oxygenated\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eTank Size:\u003c\/em\u003e Minimum 450 litres for an adult; 200 litres suits a juvenile only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eFinal Notes\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eJuveniles grow quickly, so buy with an adult-sized aquarium already planned and expect a decade or more of care. Being scaleless it is very sensitive to copper, many medications and ammonia, so keep water pristine with strong filtration and regular changes. Give it a clear tube, cave or root to hide in by day and dim lighting; with time it becomes tame enough to hand-feed, a genuinely rewarding sight.\u003c\/p\u003e","brand":"SimsTF","offers":[{"title":"Default Title","offer_id":64680676000121,"sku":"STF-KNIFE-BLK-GHOST","price":20.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1026\/3124\/4153\/files\/Black-Ghost-Knife-Fish-Apteronotus-Albifrons.png?v=1790097093","url":"https:\/\/birchwoodaquaticcentre.co.uk\/products\/black-ghost-knife-fish-apteronotus-albifrons-10cm","provider":"Birchwood Aquatic Centre","version":"1.0","type":"link"}
