Golden Whiptail (Sturisoma aureum) Care Guide
Sturisoma aureum, now placed in Sturisomatichthys, is a slender peaceful whiptail catfish from Colombian river basins that feeds mainly on plant matter.
Compiled by Aquairi from published sources · Published · Updated
Overview
Sturisoma aureum is a slender whiptail catfish in the family Loricariidae, described by Steindachner in 1900 and now placed in the genus Sturisomatichthys. It has elegant filamentous extensions on the dorsal and caudal fins and reaches about 20 cm in standard length.
Taxonomy
- Family: Loricariidae
- Scientific name: Sturisoma aureum
- Current placement: Sturisomatichthys aureus (Steindachner, 1900)
- Common trade name: Golden Whiptail
Habitat
FishBase records the species from the Magdalena, San Jorge and Cesar River basins in Colombia. It is a freshwater, demersal species of tropical climates and is associated with well-oxygenated water, submerged wood and leaf litter.
Tank requirements
- Minimum tank volume: 250 L
- Temperature: 22-26 degrees Celsius (72-79 degrees Fahrenheit)
- pH: 6.0-7.5
- GH: 2-12 dGH
- Water flow: moderate, well oxygenated
- Lifespan: 8-12 years
FishBase gives a natural range of pH 6.0-8.0 and 5-19 dH. The species does not tolerate very warm water and needs good oxygenation and bogwood.
Diet
Sturisoma aureum is largely herbivorous. A diet rich in algae and blanched vegetables such as spinach and cucumber, along with access to bogwood, suits it; small live or frozen foods may be taken occasionally.
Compatibility
The species is peaceful and bottom-oriented, suitable for community tanks with calm fish such as tetras and Corydoras. Aggressive or territorial plecos should be avoided.
Breeding
Sturisoma whiptails deposit their eggs on flat surfaces such as the aquarium glass, forming a compact mass. The male guards the eggs and fans them with his fins. Spawning is reported around 28 degrees Celsius, with clutches numbering up to about 200 eggs.
Conservation status
IUCN Red List: Data Deficient (assessed 7 October 2014).
Sturisoma aureum Breeding Guide
Overview
Sturisoma aureum, the Golden Whiptail (sometimes placed in the genus Sturisomatichthys), is a slender loricariid recorded by AquaInfo from Colombia and the western Amazon basin, reaching about 30 cm. Unlike most loricariids it is an open spawner: the female attaches an adhesive clutch to a flat surface such as the aquarium glass or wood, and the male alone guards and fans the eggs. It is regarded as a well-documented and relatively reliable whiptail to breed.
Sexing
AquaInfo states that males display small rows of spiky hairs (odontodes) along the head, which females lack. In the genus more broadly, mature males develop a fringe or beard of cheek odontodes during the breeding season, while females are stouter and rounder when carrying eggs.
Conditioning
AquaInfo notes the species prefers vegetable matter such as lettuce, cucumber, spinach, pre-cooked peas and spirulina, with live foods like mosquito larvae, Artemia and water fleas also accepted. Condition a pair or group on this varied vegetable-led diet in clean, well-oxygenated water with good flow.
Breeding Setup
Provide a mature, well-oxygenated tank with smooth vertical surfaces (glass, broad leaves, flat wood) for egg deposition and brisk current; the TFH whiptail article stresses that brisk water currents and ample oxygen are essential both for spawning and for keeping eggs and fry healthy. AquaInfo gives 25-29 degrees C, pH 6.0-7.5 and a breeding temperature up to about 30 degrees C.
Spawning Behavior & Trigger
AquaInfo reports the female lays roughly 80-100 eggs and that the male performs brood care and guards the eggs. The fish typically choose a clean flat surface in strong current. Slightly cooler, softer water changes that simulate the rainy season help trigger spawning in this genus.
Egg & Fry Care
The male guards and fans the clutch until it hatches. AquaInfo states the yolk sac is consumed after about 4 days, after which the fry can be fed Artemia nauplii, pre-cooked spinach or fine dry food tablets; the parents may be removed so they do not eat the algae the fry need. Constant access to soft vegetable matter and clean water is critical.
Common Challenges
Whiptail fry are prone to starvation if they cannot graze continuously, so a steady supply of algae and soft vegetable food is the main difficulty. Maintaining strong oxygenation and current throughout incubation and rearing is equally important.
