Sturisomatichthys leightoni is a species of armored catfish of the family Loricariidae endemic to Colombia, where it occurs in the upper Magdalena and Cauca River basins. This species grows to a length of 18cm (07inches) SL.
The Sturisomatichthys leightoni is about 14 to 18 cm long. Its upper caudal fin is longer than its lower caudal fin. Both of them are elongated and peaked.
The male Sturisomatichthys leightoni is shorter than the female one and has a short beard (1–2 mm).
The female lays about 40 eggs. The male fans fresh water on top of the eggs until the babies hatch. This takes about 6–7 days.
The catfish is named in honor of Sir Bryan Leighton (1868-1919), who presented the type specimen to the British Museum.[1]
