Missing scales in Badis can be alarming, but it's important to understand the underlying causes. This condition is often indicative of stress or disease, and timely intervention is crucial. Badis are sensitive to water quality and diet, so any deviation can lead to this issue. Owners should first ensure their fish's environment is stable and their diet is balanced.
