Tail Spot Corydoras (Corydoras Hastatus)

Tiny, active, and wonderfully distinctive — the Tail Spot Corydoras (Corydoras hastatus) is one of the smallest and most charming Corydoras species in the freshwater hobby. Like its close relative the Pygmy Cory, the Tail Spot is a mid-water schooler that darts and hovers in open water in tight groups, and is instantly recognizable by the bold black spot at the base of its tail — the feature that gives this species its common name.

Overview

Appearance

The Tail Spot Cory has a slender, semi-transparent body with a silver to pale cream colouration and a bold black spot at the base of the caudal fin — the distinctive “tail spot” that gives this species its name. A thin dark lateral stripe runs along the body. Their tiny size, active mid-water swimming style, and tight schooling behaviour make a group of Tail Spot Corys one of the most dynamic and entertaining sights in any nano or planted aquarium.
