Ornate Bichir Coughing or Spitting: Common Causes

Poor Water Quality

Most Likely

Ammonia or nitrite levels may be elevated due to overfeeding or inadequate filtration, causing respiratory distress.

Parasites

Possible

Infestations with parasites like Ich or flukes can cause irritation and coughing in Ornate Bichirs.

Stress

Less Common

Stress from overcrowding, aggressive tankmates, or rapid water temperature changes can lead to coughing or spitting.

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, nitrate, and pH levels.
Use a reliable test kit to ensure the water is within the optimal range for Ornate Bichirs.
Recommended: Water test kit
Observe the fish's behavior and appearance for other signs of illness.
Look for any changes in color, fins, or activity levels that might indicate a secondary problem.
Perform a visual inspection of the tank for signs of pests or aggression.
Ensure that tank mates are not bullying or harming the Ornate Bichir.
Examine the fish for any physical damage or parasites.
Use a magnifying glass to inspect for parasites like Ich or flukes.
Recommended: Magnifying glass
Monitor the fish for changes in behavior over several days.
Observe if coughing or spitting continues or if other symptoms develop.

How to Treat Ornate Bichir Coughing or Spitting

Improve water quality by increasing aeration and changing 25-50% of the tank water daily.
This will help to reduce ammonia and nitrite levels and provide cleaner water.
Administer anti-parasitic medication as prescribed by a vet if a parasitic infection is present.
Follow the vet's instructions for dosing and treatment duration.
Remove any aggressive tankmates or overcrowding issues that may be causing stress.
Ensure the tank provides ample space and peaceful cohabitation.
Gradually acclimate the fish to a stable water temperature, avoiding rapid changes.
Keep the tank temperature within the recommended range of 23.0–27.0°C.
Consider a temporary fasting period to reduce stress and allow the fish to recover.
Offer food sparingly for a few days to allow the fish to rest and heal.

How to Prevent Ornate Bichir Coughing or Spitting

Regular water changes, maintaining optimal water quality, and avoiding rapid changes in temperature are key to preventing coughing or spitting in Ornate Bichirs.
