Owners should first rule out common causes before taking further action.

Common Causes of Hiding Constantly in Peacock Cichlid

Aggressive Tank Mates

Most Likely

Peacock Cichlids are territorial and can become aggressive, causing the less dominant fish to hide.

Poor Water Quality

Most Likely

Unsuitable water parameters, such as high ammonia or nitrite levels, can stress the fish and lead to hiding.

Insufficient Space

Most Likely

A tank that is too small or overcrowded can cause stress and lead to hiding behavior.

Dietary Issues

Possible

An unbalanced diet or lack of nutritional variety can cause stress and hiding behavior.

New Tank Syndrome

Less Common

The initial stress of being in a new environment can cause hiding, but usually resolves with time.

How to Diagnose

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

  1. Check water parameters

    Test for ammonia, nitrite, nitrate, pH, and hardness levels to ensure they are within the optimal range for Peacock Cichlids.

    Recommended: Water test kit
  2. Observe tank mates
