Signs and Symptoms

External fish parasites can often be detected by sight. These parasites appear as spots, "dust" or tube-shaped organisms attached to the fish. You may also notice your little swimmer rubbing up against plants and other objects in the tank to try to dislodge the pesky parasites. Internal parasites can cause appetite loss, low energy and erratic swimming. Intestinal nematode infestations may produce redness and irritation around the tail area.

Treatment

If you discover a parasitic infection it's imperative that you treat it immediately to prevent it from spreading. Parasitic infections require medical treatment. Look for medications and guidance at your pet shop or veterinarian's office.

Prevention

Of course the best treatment for any harmful condition is to prevent it altogether. Follow these basic steps to help protect your finned friends.

Ensure the quality and cleanliness of live food before you feed it to your fish. Live creatures can easily introduce fish parasites.

Quarantine new fish for a few days to a few weeks before introducing them to your aquarium. Watch carefully for signs of illness or infection during the quarantine period. If you see signs of a problem, be sure the fish is treated and completely problem free before you introduce it to the community tank. Place your quarantine tank far from the community tank and use separate utensils for each to prevent possible transfer of fish parasites from one tank to the other. Careful treatment and immediate action can protect your pets from parasitic problems.
