'cory' isn't a species of fish ..Technically, a single Cory Catfish should be fine in a ten gallon tank. The problem is that Corydoras are not happy when kept by themselves. Since they are schooling fish, Cories should be kept in groups of 5 or more. For a school of 5 Cories, a minumim tank size of 20 gallons is recommended.
