Best for planted aquarium
Habitat: A Cory Catfish is a bottom dweller, so it’s a good idea to keep at least 2 inches of aquarium gravel or substrate on the tank bottom. Cory Catfish also seem to really enjoy a tank with lots of live plants. Live aquarium plants provide cover and hiding places for the fish to rest. Finally, be sure to include rocks and decorations that provide places to explore.
Aquarium pH: 7.0 – 7.8,
Temperature: 72 – 78 Degrees Fahrenheit
Lighting: Standard community tank lighting will suffice
While aquarium pH and water temperature can extend beyond the traditional community tank range, its important to maintain stability. So avoid sudden shifts in conditions. Make sure Ammonia and Nitrite levels are kept at 0 ppm, and control Nitrate buildup with regular partial water changes.
Poor Water Conditions: Cory Cats do not do well in tanks with poor water conditions. High Nitrates seem to stress Cory Cats and make them susceptible to diseases. Also avoid excessively stirring up the tank bottom while cleaning. This can release a large amount of decaying organic matter into the water column and start a bacterial bloom. The same goes for rearranging decorations. Corydoras Catfish may develop white patches around their mouths and barbels. This condition needs to be treated right away. If left untreated, Corydoras Catfish will stop eating, grow visibly thinner over time and eventually die.
Cory Catfish Diet And Feeding
Cory Catfish diet includes basic food types including fish flakes, pellets and bottom feeder tablets. Corys will spend hours on end making their way across the tank bottom poking around for food. They will even move the surface gravel around a bit with their mouths, digging for more. While their feeding ability makes Corydoras Catfish really good tank cleaners, they should not be considered a substitute for proper tank care.
While Corydoras Catfish are adept at scavenging for otherwise uneaten food, the Cory Catfish diet cannot be mere left-overs. Left-overs may be in short supply so hobbyists need to make sure Cory Cats are getting their nutritional requirements met with supplements intended specifically for them. That said, avoid the temptation to overfeed. Only feed Cory Cats an amount of food that can be eaten in about 5 minutes.
Cory Catfish Lifespan
Durable and hardy, Cory Catfish lifespan can be long compared to other fish. Cory Catfish lifespan can be 5 years, or significantly more, under the right conditions. That said, it’s not uncommon for some Cory Cats to die shortly after being added to a tank. This could be due to the stress of being transported or shifts in water parameters between home tank water and store display water. Corydoras Catfish are not as prone to this as the more delicate Otocinclus Catfish are, but it’s still a possibility worth mentioning.
