{"product_id":"black-ghost-knifefish-apteronotus-albifrons","title":"Black Ghost Knifefish (Apteronotus albifrons) 8-9cm","description":"\u003cp\u003eThe Black Ghost Knifefish (Apteronotus albifrons) is a highly unique, nocturnal freshwater fish native to the Amazon River basin. They are famous for their jet-black bodies, continuous moving bottom fin, and the weak electrical field they generate to find food and navigate in the dark.\u003c\/p\u003e\n\u003cp\u003eUnique Traits and Behavior\u003c\/p\u003e\n\u003cp\u003eElectrical Navigation: They have an electric organ that creates a weak radar system. This helps them map their surroundings and \"see\" at night. It will not shock humans.\u003c\/p\u003e\n\u003cp\u003eNocturnal Nature: They are active at night and shy during the day.\u003c\/p\u003e\n\u003cp\u003eHigh Intelligence: They can learn to trust you. Many owners train them to swim onto their hands or eat directly out of their fingers.\u003c\/p\u003e\n\u003cp\u003eMovement: They lack a dorsal (top) fin. They use a long, ribbon-like fin under their belly to swim backward and forward with equal ease.\u003c\/p\u003e\n\u003cp\u003eAquarium Setup Requirements\u003c\/p\u003e\n\u003cp\u003eHiding Spots: You must provide caves, smooth rocks, driftwood, or PVC tubes. Use a clear acrylic \"ghost tube\" so they can view the fish while it feels safely hidden.\u003c\/p\u003e\n\u003cp\u003eSubstrate: Use fine sand or smooth, rounded gravel. They do not have scales and can easily scratch their skin on sharp rocks.\u003c\/p\u003e\n\u003cp\u003eLighting: They prefer very dim or subdued lighting.\u003c\/p\u003e\n\u003cp\u003eFiltration: Strong, reliable filtration is a must. They are highly sensitive to poor water quality and sudden changes in water parameters.\u003c\/p\u003e\n\u003cp\u003eDiet and Feeding\u003c\/p\u003e\n\u003cp\u003eThey are strict carnivores. They will rarely accept dry flake food or processed pellets. Feed them right before you turn the tank lights off for the night.\u003c\/p\u003e\n\u003cp\u003eFrozen foods: Bloodworms, brine shrimp, and mysis shrimp.\u003c\/p\u003e\n\u003cp\u003eLive foods: Earthworms (chopped) and blackworms.\u003c\/p\u003e\n\u003cp\u003eDry foods: High-protein, slow-sinking carnivore pellets (if they accept them).\u003c\/p\u003e\n\u003cp\u003eTank Mates and Compatibility\u003c\/p\u003e\n\u003cp\u003eKeep only one Black Ghost Knifefish per tank. They are very aggressive toward their own kind because their electrical signals interfere with each other.\u003c\/p\u003e\n\u003cp\u003eGood Tank Mates: Medium to large, peaceful fish like Angelfish, Severums, Geophagus cichlids, Silver Dollars, and large Rainbowfish.\u003c\/p\u003e\n\u003cp\u003eBad Tank Mates: Avoid very small nano fish (like Neon Tetras or Guppies) because the Knifefish will eat them as it grows. Avoid highly aggressive fish like Convict Cichlids that might bully them.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Jasmin Aquatics Store","offers":[{"title":"Default Title","offer_id":53429881798953,"sku":null,"price":24.75,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/4325\/2521\/files\/Micro-Pellets_20260816_055649_0000.png?v=1786845446","url":"https:\/\/jasminaquaticsstore.com\/products\/black-ghost-knifefish-apteronotus-albifrons","provider":"Jasmin Aquatics Store","version":"1.0","type":"link"}
