Care guide
The giant whiptail catfish is a strikingly elongated Loricariid reported from the Magdalena, San Jorge and Cesar basins in Colombia. It has been reclassified from Sturisoma aureum to Sturisomatichthys aureus. The body is a mottled golden-brown with a dark horizontal stripe, and males develop rows of bristles along the sides of the head when mature.
The fish is slender and needs spacious quarters. Provide cover, clean water and effective circulation. Unlike many Loricariids the giant whiptail is sensitive to deteriorating water conditions. Driftwood and sturdy plants such as Anubias suit its natural perching behaviour.
The giant whiptail feeds primarily on algae and biofilm. In captivity it requires a well-lit tank that encourages algal growth, supplemented with blanched vegetables and spirulina-based sinking foods. Watch that this quiet feeder gets its share of food rather than relying on other fish's leftovers.
Extremely peaceful and somewhat shy, this catfish should not be housed with boisterous tankmates or fin-nippers. Good companions include angelfish, tetras, Corydoras and other quiet community fish. Breeding has been achieved in aquaria with the male guarding the eggs.
