Fresh stock in: Black Arowana (Osteoglossum ferreirai), 12β13 inches β 6 available at Β£250 each.
This is one of the more demanding species we carry, and we'll be straight with you about that. O. ferreirai is the rarer, darker South American cousin of the Silver Arowana β found in the Rio Negro and its blackwater tributaries. Juveniles arrive with striking banding that fades to a deep gunmetal as they mature. Adults regularly reach 90cm+ in captivity, and they grow quickly.
π Tank: minimum 6Γ2ft footprint to start, larger as they grow
π§ Water: blackwater conditions, pH 5.5β7.0, 26β30Β°C, soft (under 8 dGH)
π Feeding: surface-feeding predator β live insects, prawns, earthworms; wean onto Hikari Massivore or similar large sticks over time
π Lids: secure, heavy, no gaps β they jump. Full stop.
These are not a fish for a community tank or a 4ft setup. If you have the space and the setup, they are genuinely remarkable animals.
