Cory Catfish come in a modest but appealing array of colors, from different shades of browns and grays to occasional flashes of metallic or golden hues.

Cory Catfish Tank & Water Requirements

Taking care of a Cory Catfish requires attending to its habitat requirements and maintaining a conducive water environment.

Habitat and Tank Requirements

To create conditions close to their natural habitat, a Cory Catfish tank should ideally start at 10 gallons, with each additional fish requiring an extra 2 to 4 gallons. They enjoy gently moving waters with soft substrates, preferably sand, as their barbels can easily get injured on rough surfaces. These fish are adapted to low-light environments, so a dim-lit tank with plenty of plants would help emulate their native freshwater rivers.

Water Conditions

To ensure your Cory Catfish thrives, maintain Cory Catfish temperature between 70°F to 80°F. The water pH levels hold equal importance, ideally hovering between 6.0 to 8.0. Lastly, the ammonia and nitrite levels should always be kept at 0 ppm to prevent any harm to these gentle creatures.
