Getting Rid of the Water Mites

If water mites become a nuisance to your fish, it is important to take steps for eliminating them. These five tips can help you get rid of these tiny critters from your tank:

1. Do Nothing:

You may not need to do anything if the water mites are not bothering your fish. However, it is important to keep an eye on the population of mites in the tank to ensure they don’t grow out of control and potentially cause infections.

Adult mites typically remain in the substrate and will only bother your fish if they do not have enough food. If this is the case, you may want to consider adding more food or changing their environment to give them a more plentiful source of sustenance.

2. Manually Removing Mites:

Manual extraction is an effective way to get rid of mites in an aquarium. You can use a siphon or a turkey baster to suck the mites up or use a toothbrush or paintbrush to scrub the glass sides of your tank and then suck them up with a siphon.

It may require some effort, but it is far better than dealing with a larger infestation down the line. Remember to take time to inspect every nook and cranny of your aquarium for mites so that you can treat them as early as possible.

3. Modify the Tank:

Water mites can be a nuisance in an aquarium and can cause stress to fish, leading to illness or even death. To help eliminate these pests from your tank, it is important to use the right filter. Canister filters are great for this purpose as they offer powerful filtration that can trap and remove small particles such as water mites.

In addition to filtering out the bugs, it’s also a good idea to keep an eye out for other signs of infestation such as eggs or webs in the tank. Regularly cleaning and maintaining your tank will help decrease water mite populations.

4. Deep Clean and Maintain Your Aquarium:

The frequency of cleaning your fish tank can vary depending on the number of fish you keep and other factors. Generally, it is recommended to clean your tank once a week or once a month if you have fewer fish.

In cases where there are water mites present in the aquarium, it is best to deep clean the tank biweekly. Deep-clean servicing involves vacuuming the substrate, wiping glass surfaces, inspecting of the filter, and assessing water quality.

It is important to perform necessary pruning to plants, as well as changing out dirty water when needed. Overall, proper maintenance and regular cleaning are essential for a healthy home for your fish.

5. Vacuum Aquarium Gravel To Remove Fish Food Remains:

It is important to avoid overfeeding your fish. Eating too much can cause uneaten food particles to linger in the tank, leading to an infestation of aquarium mites. To prevent this, remove any remaining food after feeding and consider using a gravel vacuum cleaner or siphon to regularly clean up the substrate in your tank.

You should also monitor the amount of food you are giving your fish, as too much can cause the water quality in your aquarium to deteriorate and lead to other issues. Taking these steps will help ensure that your fish remain healthy and safe from aquarium mites!

6. Check the Water Parameters:

Maintaining a healthy aquarium is key to preventing an outbreak of water mites. It is important to monitor water parameters, including pH, temperature, ammonia, and nitrate levels on a regular basis. Frequent water changes can help keep parameters stable and reduce the chance of overpopulation.

Additionally, making sure to use only clean and safe materials in your tank will help maintain the water quality and prevent contamination from chemicals or parasites.

7. Installing a Powerful Filter:

HOB filters are a great tool for eliminating aquarium mites, as they suck up tank water through a siphon tube and pump and pass it through different media layers to trap the floating mites. Additionally, HOB filters often generate strong currents which can help dislodge mites sticking to plants and decorations.

However, these filters may not be able to clear all the aquarium mites entirely as some of them may hide in crevices that are out of reach.

8. Adding Mite-Eating Aquatic Life:

Adding mite-eating aquatic life to a fish tank can help remove small brown bugs. Some species that you can add to your tank to help keep pests away include Plecostomus, Siamese Algae Eaters, Chinese Algae Eaters, and Malabar Gudgeons.

Mandarin fish

Pterosynchiropus splendid, or the Mandarin Dragonet, is a stunning addition to any reef tank. Not only are they visually stunning, but they also help to keep pests like mites in check. However, caring for them is not for beginners – as picky eaters, they require dedicated care and a proper diet to ensure their longevity in captivity. It’s important to have an understanding of their specific dietary and care needs before introducing them into your tank.


Angelfish belong to the Cichlidae family and are commonly kept in freshwater aquariums. Known for their beauty and graceful swimming pattern, these fish can be found in the South American tropics. As omnivores, they will eat both flakes and live food such as brine shrimp.

Further, angelfish are renowned for foraging around the tank’s substrate in search of crustaceans and worms to eat. This behavior makes them great killing machines when it comes to dealing with mites in the tank. Therefore, angelfish are an ideal choice for aquarium owners wanting to keep mites out of the aquatic environment.


Nemateleotris Magnifica, more commonly known as Firefish, are a beautiful and peaceful species of fish found in the Indian and Pacific oceans. They have vibrant colors, elongated bodies, and long dorsal fins. Firefish are omnivores and enjoy eating zooplankton, shrimp, and small crustaceans, making them great mite feeders for saltwater tanks.

Additionally, they require minimal care and do well in community tanks, making them a great choice for beginner aquarium enthusiasts.

Guppy fish

Guppies, or Poecilia reticulata, are a popular choice for beginner aquarists due to their hardiness and ease of care. These fish are known for being top level swimmers but can also be helpful in controlling mites and other small crustaceans that may be present in the tank. Guppies are peaceful and generally keep to themselves, making them an excellent addition to any aquarium.

Additionally, these fish are easy to breed and provide plenty of stimulation for your tank inhabitants.

9. Use a chemical treatment like Aquari-sol:

Aquari-sol is a chemical that can be used to target and kill aquarium mites, as well as fish diseases like Ich. It should not cause any stress on your fish and is a safe method of eliminating these pests from your tank.

The recommended dosage for Aquari-sol is 12 drops per 10 gallons of water. This concentrated solution will eliminate the mites without harming your fish, as well as reduce algae growth which could attract more aquarium mites.

Additionally, frequent water changes can help to control the population of aquarium mites and reduce their overall numbers in the tank. Therefore, if you notice an abundance of aquarium mites in your tank, Aquari-sol might be worth considering when looking for an effective treatment.

10. Perform a 10% or 20% water change each week:

Mites can be a problem for any fish tank, small or large. Luckily, there are some steps you can take to reduce the population of mites in your aquarium. Regularly performing water changes is an effective way to lower the mite population in your tank.

For small tanks with water below 50 gallons, you should change 10% of the water each week. If your tank is larger than 50 gallons, then it’s best to perform a 20% water change each week to help keep the mite infestation under control.

11. Treating With Aquari-Sol:

The use of Aquari-sol as a treatment for mites is not an officially recommended practice, and there is limited information about the ingredients of the medication. However, it appears that Aquari-sol likely contains copper, which is a common ingredient in medications used to treat Ich. Copper is known to disrupt the respiratory processes of invertebrates like shrimp or snails, which could explain why Aquari-sol might be effective against aquarium mites.

However, any treatments containing copper should not be used in tanks with shellfish or other invertebrates. In this instance, it’s best to consult with an aquatic veterinarian who can recommend a safe and reliable treatment option. Additionally, always consider any possible side effects before administering treatment to your fish tank inhabitants.
