A Unique and Graceful Bottom-Dweller
The Long Nose Whiptail Catfish (Sturisoma barbatum) is a striking freshwater fish, admired for its elongated body, delicate fins, and peaceful nature.

Caring for the Long Nose Whiptail Catfish
This species thrives in aquariums of at least 100 liters, with fine sand or smooth gravel substrates to protect their delicate undersides. They prefer a well-oxygenated tank with moderate water flow, plenty of driftwood, and shaded hiding places. Maintain water temperatures between 22°C and 28°C, with a pH range of 6.0–7.5. Weekly water changes and efficient filtration help ensure a stable environment.
 
Ideal Tank Mates
The Long Nose Whiptail Catfish is peaceful and does well in community aquariums. Good tank mates include small tetras, rasboras, peaceful cichlids, and other non-aggressive bottom dwellers like Corydoras or Otocinclus. Avoid keeping them with overly aggressive or fin-nipping species.
 
Feeding the Long Nose Whiptail Catfish
These omnivorous catfish primarily graze on algae but should be supplemented with high-quality sinking pellets, algae wafers, and blanched vegetables like zucchini or spinach. They also appreciate occasional protein-rich foods such as bloodworms or brine shrimp. Providing a varied diet ensures they remain healthy and active.
 
Breeding Long Nose Whiptail Catfish
Breeding this species requires stable water conditions and a well-structured environment. Males guard eggs laid on smooth surfaces like driftwood or tank glass. After hatching, the fry feed on biofilm and require powdered fry food or finely crushed algae wafers for proper development.
