How to Fix Swim Bladder Disease in Goldfish

A fish that has problems diving to the bottom of its tank, appears stuck at the bottom of the tank seemingly unable to swim to the surface, swims sideways or upside down or appears to swim standing on its head, might have Swim Bladder Disease--an illness that affects a fish's equilibrium. Treating Swim Bladder Disease is not complicated and involves using green peas you find in your own freezer.

Things You'll Need

Instructions

    • 1

      Defrost 1 to 2 frozen peas. The peas must be very soft. If they are not soft enough for a fish to eat, cook them briefly according to the package directions.

    • 2

      Gently squeeze the peas to free them from their skins. Discard the skins.

    • 3

      Put the skinless peas in the fish tank.

    • 4

      Allow the affected fish to eat at least 1 of the 2 peas. If there are healthy fish in the tank, either remove them so that they will not eat the peas, or remove the sick fish into a separate tank and offer the peas there. If the sick fish will not eat the peas, remove the peas and try again later.

    • 5

      Withhold other foods until the sick fish eats at least 1 pea.
