Common Causes of Missing Scales in Kissing Gourami

Poor Water Quality

Most Likely

Ammonia and nitrite levels can cause stress leading to scale loss.

Bacterial Infection

Most Likely

Gram-negative bacteria such as Aeromonas can cause scale loss and skin lesions.

Internal Parasites

Possible

Parasitic infections can lead to skin damage and scale loss.

Fungus

Possible

Fungal infections like Saprolegnia can cause scale loss and a cottony appearance.

Environmental Stress

Less Common

Changes in water parameters or tank conditions can stress the fish and lead to scale loss.

How to Diagnose

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

  1. Inspect the fish for signs of injury, fungus, or parasites.

    Look for red spots, ulcers, or cottony growths.

    Recommended: magnifying glass
  2. Test the water parameters for ammonia, nitrite, and nitrate levels.

    Use a test kit to ensure the levels are within the appropriate range.

    Recommended: water test kit
  3. Observe the fish's diet and feeding habits.

    Ensure a balanced diet rich in vitamins and minerals is being provided.

  4. Check the water temperature and pH level.

    Verify that these are within the recommended range for Kissing Gourami.

  5. Consider recent changes in the tank environment or diet.

    Identify any recent changes that may have caused stress to the fish.

How to Fix It

  1. Perform a partial water change to improve water quality.

    Change 25-30% of the water every week to maintain healthy parameters.

  2. Administer appropriate medication based on the diagnosis.

    Follow the treatment regimen recommended for the specific condition (e.g., antibiotics, anti-fungal).

  3. Increase the diet of vitamin C and omega-3 fatty acids.

    These can help support the fish's immune system and aid in recovery.

  4. Ensure the tank temperature is within the optimal range.

    Keep the water temperature at 22.0–28.0°C to prevent further stress.

  5. Provide hiding spots and reduce stress factors in the tank.

    This includes reducing tank noise and avoiding rapid water currents.

Prevention

Regular water changes, maintaining optimal water quality, and providing a balanced diet can prevent missing scales in Kissing Gourami.
