Knob Nose Whiptail Catfish


Family: L oricariidae
Species: Hemiodontichthys acipenserinus
Common Name: Knob Nose Whiptail Catfish, Knobnose Whiptail Catfish, Pinocchio Whiptail Catfish
Size: Adult Male: 5.28 inches (13.4 cm)
Habitat: SOUTH AMERICA: Bolivia, Brazil, French Guiana, Guyana and Peru: in the Amazon, Essequibo, Oyapock and Paraguay River basins.
Min Tank Size: individual: 18.49 gallons (70 liters) or larger Shoal of 4: 39.63 gallons (150 liters) or larger Each fish must have a minimum of 24 square inches of tank floor.
Diet: Omnivore: Enjoys worms and micro-crustaceans in nature; in aquaria, provide live and frozen blood worms, Cyclops, daphnia, mysis shrimp, and tubifex worms. Supplement with sinking carnivore tablets and algae tablets with a slice or cucumber or zucchini for an occasional treat.
Behavior: Peaceful, very shy and retiring catfish lies still for long periods.
Water: Temperature of 75 to 82°F (24 to 28°C), pH range: 6.0 7.0; dH range: 2.0 - 12.0
Care: Moderate to advanced. Sand substrate is essential as this catfish partially buries itself as a form of camouflage. Immaculate, highly-oxygenated water with a moderate amount of current is essential.
Communities: Peaceful tankmates include small characins, dwarf cichlids, and smaller Corydoras. This very gentle fish needs to be the only bottom-dweller in the aquarium as it can be easily out-competed for food. Does best in a one male to one female ratio.
Suitability: Some experience required.
Note: This is an unusual fish to find in aquaria for while they're not rare in nature, many losses occur in transport due to oxygen-starvation.
