As for their appearance, they are mostly bilaterally symmetrical, elongated, and usually tapered at both ends.

Furthermore, they secrete an external cuticle that is periodically molted, just like arthropods and members of six other phyla.

Simply put, nematodes thrive in dirty water. Since the high number of bacteria in the water lowers the immune system of fish, this encourages nematodes to multiply more easily while infecting your pets. To avoid this, you need to make sure the water is clean. A quality filter and regular water changes will help you the most.

In addition, it is important to emphasize that nematodes thrive in warm water conditions. That is why it is important to avoid heating the water to more than 800F if you want to reduce their population.

Treating Infection In Aquarium Pets

If you are wondering how to get rid of nematodes in the aquarium, you can simply add dewormer to your pet’s food. The most effective drugs for treating nematode infection that are also FDA-approved include Fenbendazole, Levamisole, Piperazine, Flubendazole, and Pyrantel Pamoate.

It is important to emphasize that they do not kill nematodes, but paralyze the jaws around the worms that hold the fish’s entrails. Once paralyzed, the worms will be completely removed from the fish’s gut.

Tip: Separate the infected fish in a quarantine tank that has no substrate at the bottom. This will allow you to easily spot and remove worms from your aquarium tank.

Giving Medicine To Your Aquatic Pets

Another answer to the question of how to get rid of nematodes in the aquarium is medications. Namely, medicines should be mixed with food in a ratio of 1 to 5.

The process goes like this:

  • Heat about a quarter cup of water in a microwave for a few minutes.
  • Mix about a quarter ounce of medication in hot water and stir well.
  • Mix the heated water with two tablespoons of commercial fish food and stir until you get a paste-like texture.

Feed your fish this medicinal mixture for about a month.

Treatment Of An Infected Aquarium

In order to remove all the remaining parasites, it is necessary to treat the aquarium tank itself. To treat the tank, you should add about 2-milligram of any of the above medications per liter of aquarium water. Leave on for about 24 hours, and then change at least 70% of the water. Note that the substrate must be thoroughly vacuumed. This treatment should be repeated after 2 weeks and again at 5 weeks.

This was the last answer to the question of how to get rid of nematodes in the aquarium.
