In addition to the ideal temperature range, platys also require a stable pH level between 7.0 and 8.0. Water that is too acidic or too alkaline can cause health problems for platys, such as stunted growth, weakened immune systems, and skin problems.
To ensure that your platys have a healthy and comfortable environment, it is important to monitor the temperature and pH level of your aquarium water. You can use a thermometer to measure the temperature and a pH test kit to measure the pH level. If necessary, you can make adjustments to the temperature or pH level by using an aquarium heater or a pH adjuster.
