Cory catfish red blotch disease fish is another common ailment among Cory catfish is characterized by red spots on Cory catfish bodies, head, or fin edges from excessive scratching against hard surfaces
due to parasites or bacterial disease often aggravated by poor conditions such as high toxicity levels in the water or low oxygen saturation levels caused by an overcrowded aquarium tank or lack of filtration system Symptoms often include reddish-brown spots on the skin,
Corys developing along lesions that make it difficult for them to swim correctly., Clamped fins will eventually lead to fin rot, affecting multiple areas of the fish’s body, including cory catfish red gills, dorsal fin, anal fin, etc.
