Symptoms Of Fin Rot Cory Catfish
In the water of a fish tank, there are numerous bacteria. Your Cory’s immune systems prevent illness from spreading, so these germs don’t affect them.
The ecology of your aquarium depends on bacteria to function properly.
Nevertheless, when your fish is under stress, their immune system may be weakened, enabling germs to establish a foothold and spread illness.
Aeromonas, Vibrio, or Pseudomonas bacteria are the most likely species to result in fin rot. Fins with fin rot will first have edges that discolor and seem milky in the early phases.

Overcrowding
The basic general rule for stocking an aquarium is one inch of catfish for each water gallon.
