The Tire Track Eel, a solitary bottom dweller, often jumps out of the tank due to stress or environmental issues. This is an emergency as it can lead to injury or death. Owners should first assess the tank conditions and behavior changes before taking action.
Tire Track Eel Jumping Out of Tank: Common Causes
Poor Water Quality
Most LikelyHigh ammonia or nitrite levels can stress the fish, prompting it to jump out of the tank.
Insufficient Oxygen
Most LikelyLow dissolved oxygen levels in the water can cause the eel to surface for air, leading to frequent jumping.
Improper Tank Size
Most LikelyIf the tank is too small or the eel feels threatened, it may attempt to escape by jumping out.
Dietary Issues
PossibleA lack of appropriate food or overfeeding can cause stress and erratic behavior.
Poor Tank Aesthetics
Less CommonA cluttered or unsightly tank may stress the eel, leading to jumping out.
How to Diagnose the Cause
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Check water parameters for ammonia, nitrite, and nitrate levels.
Use a water test kit to ensure the water quality is within the optimal range for Tire Track Eels.
Recommended: Water test kit - Monitor the water temperature and pH levels.
Ensure the temperature is between 22.0–28.0°C and the pH is between 6.5–7.5, as these are the ideal conditions for Mastacembelus armatus.
- Assess the tank size and decorations.
Confirm that the tank is adequately sized and that the decorations are not causing the eel to feel threatened or trapped.
- Observe the diet and feeding routine.
Ensure the Tire Track Eel is receiving a balanced diet that meets its nutritional needs.
- Evaluate the tank's cleanliness and overall aesthetic.
Check for any factors that may be causing stress, such as excessive algae growth or sharp decorations.
How to Treat Tire Track Eel Jumping Out of Tank
- Improve water quality by performing regular water changes and treating any ammonia or nitrite spikes.
Replace 25-30% of the tank water weekly to maintain a healthy environment.
- Increase aeration or consider using an air stone to improve oxygen levels.
This can be done by adding more plants or using an air pump to ensure adequate oxygenation.
- Ensure the tank size is appropriate and provide hiding spots if necessary.
If the tank is too small, consider upgrading to a larger one with more space for the eel to move around.
- Adjust the feeding routine to provide balanced nutrition and avoid overfeeding.
Feed the Tire Track Eel small, frequent meals and remove any uneaten food after 5 minutes.
- Improve the tank's aesthetics and remove any stressors.
Keep the tank clean and well-maintained, and consider adding more live plants or smooth rocks for hiding spots.
