Common Causes of White Spots (Ich) in Cleaner Wrasse

Poor Water Quality

Most Likely

Ammonia, nitrite, and nitrate levels above recommended can stress the fish, making them more susceptible to Ich.

Stressful Conditions

Most Likely

High temperature fluctuations, overcrowding, and aggression can weaken Cleaner Wrasse, predisposing them to Ich.

Introduction of Diseased Fish

Possible

New fish may introduce Ich into the tank, as the parasites can survive in the water column.

How to Diagnose

  1. Inspect the fish for visible spots

    Look for salt-grain-like spots on the skin and fins. White spots indicate Ich.

  2. Observe for symptoms

    Look for clamped fins, erratic swimming, and gasping at the surface. These are signs of Ich.

  3. Consider tank conditions

    Assess water quality and tank mates. Stress or poor water conditions can exacerbate symptoms.

How to Fix It

  1. Remove the affected fish and isolate

    Keep the affected Cleaner Wrasse in a separate, properly cycled tank to prevent spreading to other fish.

  2. Heat the tank water to 27.5–28Β°C

  3. Perform daily water changes

    Change 20% of the tank water daily to remove dead parasites and relieve stress. Use dechlorinated water.

Prevention

Regularly monitor water parameters and maintain stable water quality. Avoid overcrowding and sudden temperature changes. Introduce new fish into the tank gradually.
