Pygmy Corydoras
Corydoras pygmaeus
Callichthyidae
About
The pygmy corydoras is one of the smallest catfish in the hobby, a silvery nano fish with a bold black lateral stripe. Unusually for a cory, it spends much of its time hovering and swimming in mid-water as a coordinated shoal rather than only patrolling the bottom. Best kept in large groups in a peaceful nano aquarium, where its schooling behaviour is a constant delight and it feels secure.
Care
Keep 8+ (ideally 10+) in a calm, well-planted nano tank with soft sand and gentle flow. Only house with tiny, peaceful tankmates as it is easily eaten or outcompeted.
Diet
Omnivore with a very small gape; offer micro-foods such as baby brine shrimp, crushed flakes and frozen cyclops. Target-feed to ensure it eats.
