Description
Overview
The Sturisoma rostratum, commonly known as the Curved Nose Whiptail Catfish, is a striking freshwater fish prized for its elongated, slender body and distinctive whisker-like extensions. This peaceful bottom-dweller is a member of the Loricariidae family and is well-suited for community aquariums. Its unique appearance and gentle nature make it a popular choice among catfish enthusiasts.
Origin
Sturisoma rostratum is native to the slow-moving rivers and tributaries of South America, particularly in regions of Colombia and Venezuela. These fish thrive in environments with sandy or fine gravel substrates, submerged driftwood, and plenty of hiding spots.
Feeding
Whiptail Catfish are omnivorous with a preference for plant-based foods. Their diet should include:
Algae wafers and spirulina-based foods
Blanched vegetables like zucchini, spinach, and cucumber
High-quality sinking pellets
Occasional protein sources such as bloodworms or brine shrimp
They are efficient algae grazers but should not be relied upon as the sole means of algae control in the aquarium.
Tank Mates
Sturisoma rostratum is a peaceful species that coexists well with other non-aggressive fish. Ideal tank mates include:
Tetras, Rasboras, and other small schooling fish
Dwarf Cichlids such as Apistogramma
Corydoras catfish
Gouramis
Other peaceful Loricariids
Avoid keeping them with aggressive or highly territorial species such as large Cichlids.
Aggression
This species is extremely peaceful and does not exhibit territorial behavior, making it an excellent choice for community aquariums. However, they can be outcompeted for food by faster or more aggressive feeders, so targeted feeding is advised.
Experience Level
Sturisoma rostratum is best suited for aquarists with at least an intermediate level of experience. While they are relatively hardy, they do require stable water conditions and a well-maintained tank with sufficient oxygenation and filtration.
Water Parameters
Temperature: 22°C – 28°C (72°F – 82°F)
pH Level: 6.0 – 7.5
Hardness: 2 – 12 dGH
Tank Size: Minimum 30 gallons for a single fish; larger tanks are preferred for groups
Maintaining clean water with regular water changes and avoiding excessive nitrate buildup is essential for their health and longevity.
