Housing
Peppered corys can be kept in a tank as small as 10 gallons (38 litres), but to provide them with the best possible environment, it’s recommended to provide them with at least a 20 gallon (70 litre), long tank. As they spend much of their time on the bottom of the tank, the dimensions of the bottom are more important than its height.
They are a very peaceful fish, and even during mating they rarely show aggression to each other. Because of this, they can easily be kept with any other peaceful community fish, and they are perfect for most tetras, danios and even some small cichlids.
Peppered corys are a schooling fish, and should be kept in groups of at least five or more at all time. To truly experience their natural behavior, many aquarists recommend keeping them in groups of ten or more, which will both reduce their stress levels, and provide you with impressive displays of schooling.
Because they constantly root for food in the substrate with their sensitive barbels, gravel or other sharp substrates should be avoided. In fact, anything sharp in the aquarium can damage their barbels, so choose decorations with care, and a small grain sand is usually the best choice for the substrate.
In addition to a soft substrate, their tank should also include numerous aquatic plants, with plenty of driftwood or decorations that they can hide in. They prefer a dimly lit aquarium, or barring that – one that is heavily shaded from thick plant growth.
Filter
While they are known as hardy fish, they should still be provided with an excellent filter. One of the best filters to choose for a peppered corydoras tank is a hang on back filter. These filters are known for their durability, and provide pristine water conditions if they well maintained.
If you decide to use to a hang on back filter, I would strongly recommend that you use an AquaClear Power Filter. This is a highly durable filter, which provides excellent filtration even on larger tanks. You can read the Aquarium Tidings Aquaclear Power Filter Review here.
