Common Causes of Not Eating in Convict Cichlid

Aggressive Tank Mates

High ammonia or nitrite levels can stress the fish and cause them to stop eating.

Stress from Tank Decor

Possible

Disease

Possible

Dietary Issues

How to Diagnose

Follow these steps in order. Stop when you identify a likely cause and move to treatment.

  1. Check the water quality
