Ideal living conditions
Cory catfish are hardy fish and can live in a wide range of water conditions and parameters.
Provide them with their ideal living conditions, and they will thrive.
To provide them with good living conditions, you have to ensure their ideal water conditions and parameters.
Cory catfish are freshwater fish and prefer to live in clean water conditions.
To ensure clean water conditions, consider performing a weekly water change of at least 35%.
Also, add a good filtration system to protect the water from harmful toxins like ammonia and nitrite.
|Water condition||Clean water condition|
Make sure to maintain the ammonia and nitrite level at 0ppm, whereas nitrate should be below 20ppm.
We recommend using the API master kit to check ammonia, nitrite, and nitrate levels regularly.
You can buy it from amazon: API FRESHWATER MASTER TEST KIT.
Also, you can check the pH level of your cory catfish tank using the API master test kit.
|Water Temperature||Between 70-82 °F|
|Water pH level||Between 7 and 8|
|Water TDS level||Between 400-600ppm|
|Water Hardness||Between 5 and 19 dGH|
To ensure the ideal water parameters of your cory catfish, make sure of all these things:
- Provide them with a water temperature between 70-82 °F.
- Keep the water pH level between 7 and 8.
- The water TDS level of your cory catfish tank should be between 400-600ppm.
- The general hardness of the water should be between 5 and 19 dGH.
Also, consider adding a heater to your cory catfish tank to stabilize the water temperature.
Unstable water temperature will make them come under stress and become prone to diseases and parasites, affecting their growth.
