Common Causes of Floating at Surface in Gold Nugget Pleco

Bacterial Infections

Possible

Stress

Less Common

Stress from tankmates or sudden changes in the environment can cause temporary surface floating.

How to Diagnose

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

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

How to Fix It

    Follow the vet's instructions for dosage and treatment duration.
