A sturdy Argentinian cory with a pale body covered in dark spots and a striking tall dorsal fin that grows especially long in mature males. It is kept for its unusual finnage, peaceful nature and tolerance of cooler water than most corydoras.

Breeding

Spawns in typical cory T-position, with the female sticking adhesive eggs to glass and plants, often triggered by a cool water change. It breeds fairly readily in captivity and the fry are easy to raise on microfoods.

Good to know

Comes from subtropical waters, so avoid keeping it permanently warm with discus or similar species. Use soft sand to protect its barbels.
