Overview
The barred-tail cory is a peaceful schooling cory that works the bottom of a community tank. It suits a keeper with a little experience.
Did you know
The barred-tail cory's small size makes it one of the few cories that fit a nano tank. Like other cories, it can gulp air from the surface and absorb oxygen through its gut. That backup breathing trick helps in the low-oxygen pools where it sometimes lives.
Caring for the barred-tail cory
Keep barred-tail cories in a group of at least six, since a lone one is stressed and inactive. A tank of at least 13 gal (50 L) suits them, with soft sand, hiding spots, plants and shade. They sift the substrate constantly, and sharp gravel wears down their barbels.
Keep the flow gentle and the water at 70 to 82°F (21 to 28°C), with a pH of 6.0 to 7.5. Feed sinking pellets and wafers plus frozen bloodworms or brine shrimp. Make sure food actually reaches the bottom, where they work all day.
Barred-tail cories are peaceful and safe with other community fish. They are egg scatterers with no parental care, and the eggs hatch in roughly three to five days.
Good to know
The barred-tail cory, Hoplisoma cochui, is a small armored catfish in the family Callichthyidae. Its common name comes from the dark bars on its tail fin. Wild populations face pressure from deforestation and pollution, but they are not formally listed as endangered.
In the wild
Barred-tail cories come from clear, slow streams and small tributaries in the Rio Araguaia basin in Brazil. They live over sand and mud with plant cover.
