Injury
Most LikelyPhysical injuries from fighting or handling can provide an entry point for fungi, leading to fungal infections.
Poor Diet
PossibleA diet lacking in necessary nutrients can weaken the fish's immune system, contributing to the development of fungal infections.
Unsuitable Tank Conditions

How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Inspect the fish for signs of injury or stress.
Look for any cuts, scratches, or signs of aggression that could have caused the injury.
