Bottom-dwelling fish like cory catfish can play an essential role in keeping your tank clean. Their mouths and scales can scrape the debris off the bottom of the tank, which helps to prevent build-up over time. In addition, they can clean their tanks with the algae that they scrape off.

Keeping Cory Catfish in Aquariums

Habitat and Behavior

Cory catfish are native to the rivers and streams of South America. They vary greatly in coloration, but all share a common feature- they are algae eaters. Keeping them in an aquarium with clean water and good quality protein food is essential for their health and happiness. Corys tend to be calm fish that prefer hiding places among rocks and plants, so providing plenty of these will make them feel at home in your tank.

Aquarium Size

Cory catfish are suitable for the home aquarium only as a small addition to an existing fish community. However, they are not suited to be kept alone and need adequate space both in terms of length and width. For example, a 12-inch Cory will require a tank measuring at least 18 inches wide by 24 inches long, while 3-inch corys will do well in tanks up to 10 inches wide by 20 inches long.

Plants and Decorations

Providing plants and floating decorations is an excellent way to add depth and visual interest to your cory tank. Good choices include stemless water lilies, sword blennies, java ferns, crypts, aquatic weeds, or bogwood blades. In addition, fish in your cory tank should have an excellent home-based decoration. Different types of colorful small fish will improve the visual interest and engage more active play from your corys, which is very important for their overall happiness when kept as an aquarium pet.

Feeding

Cory catfish are avid feeders and should be given a diet that consists primarily of quality protein. They enjoy things like sinking pellets, small crustaceans, and live insects. In addition, they have a reputation for being bad with smaller fish, so caution is recommended when introducing them to other active species. In addition, make sure the tank is large enough for them to swim around in, and they can get ample food and hiding spots.

Temperament

Cory catfish are peaceful fish that you can keep in most community aquariums without fear of aggression from other tankmates. However, they should not be housed with large, aggressive fish or those with solid finning tendencies as they may be unable to defend themselves. In addition, in the wild, cory catfish live in strongly oxygenated water full of plant life, so they may not be as decorated with small plants and other decorations.

Water Parameters

The water parameters needed for cory catfish vary depending on the species and variety. Still, typically they will require a substrate of sand or gravel, live plants, dimmable lighting, and room temperature of 74 to 80 degrees Fahrenheit (21 to 27 degrees Celsius). In addition, they should be kept in an aquarium for at least 20 gallons.

Tankmates

Best tank mates for cory catfish vary depending on their personalities. Still, generally, they should be kept with other similar-sized species of fish that are neither too aggressive nor timid. Some popular choices include tropical fish such as gouramis and Siamese fighting fish.
