Sinking to the bottom is a critical sign in Tire Track Eels, often indicating a severe health issue. This behavior is highly urgent as it can lead to suffocation. Owners should first assess the water quality and diet, as these are primary factors.

Tire Track Eel Sinking to Bottom: Common Causes

Poor Water Quality

Most Likely

Ammonia, nitrite, or nitrate levels can be toxic to Tire Track Eels, causing them to sink to the bottom as a stress response.

Inadequate Diet

Most Likely

Insufficient nutrition or an unbalanced diet can lead to weakness and a loss of buoyancy control.

Stress

Possible

Stress from tank mates, tank conditions, or handling can cause Eels to become lethargic and sink to the bottom.

Internal Health Issues

Possible

Conditions like internal parasites or organ failure can cause Eels to lose their ability to swim normally.

Physical Injury

Less Common

An injury from tank decor or aggression can impair the Eel's ability to swim properly.

How to Diagnose the Cause

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

  1. Test the water parameters for ammonia, nitrite, and nitrate levels.

    Use a reliable test kit to ensure the water quality is within the recommended range for Mastacembelus armatus.

    Recommended: Water test kit

    Ensure the Eel is receiving a balanced diet that includes a variety of live, frozen, and freeze-dried foods.

  3. Check the tank for any signs of aggression or stress.

  4. Inspect the Eel for any physical injuries or signs of parasites.
