Causes Of Stress In Cichlids
Cichlids are popular aquarium fish but can easily get stressed. Stress affects their health and behavior.
Knowing what causes stress helps keep cichlids healthy and happy in their tank.
Water Quality Issues
Poor water quality is a main cause of stress for cichlids. Dirty or toxic water harms their gills and skin.
High ammonia, nitrite, or nitrate levels can make fish sick and weak. Unstable pH also upsets them.
- Keep ammonia and nitrite at zero
