What Are Water Mites?


If you’re spotting tiny critters in your fish tank, chances are they’re water mites. These tiny bugs play a big part in keeping everything balanced. They tend to show up more when something in the tank isn’t quite right. You’ll often find types like amphipods, copepods, ostracods, and daphnia.

The good news is, your fish probably love snacking on them. If things are going well, these mites can even make up a big chunk of your fish’s meals. But watch out, because some mites can hurt your fish. So, always keep an eye on things and make sure the mites aren’t taking over.

Types Of Water Mites

  • Spider-type Mite: This mite is characterized by distinct head and body segments. It tends to crawl along the inner and outer surfaces of the tank, including those submerged and above water.
  • Shrimp-type Mite: These mites resemble tiny semi-circle dots. They primarily float around in the water, often near aquatic plants and algae.
  • Crystal-type Mite: Identified by their odd-shaped floating specs, either white or black, these mites typically adhere to surfaces and objects inside the aquarium, both above and below the waterline.

Are Water Mites Harmful To Humans?

The water mites are not able to live on human beings. Neither are they known for transmitting any disease to humans. The fish population and the aquatic plants suffer due to the presence of water mites in the pools as well as the aquariums. 

The mites cannot survive on the body fluids they suck out of the human body. They cannot even reside on top of it. This is good news for people searching for ways to get rid of the mites from their pools. 

You can easily do whatever you want without putting yourself in harm’s way. Though mites are small many, you can have a single solution for the entire problem. 

Are Water Mites Harmful To Fish?

Yes, water mites are undoubtedly harmful to the fish in the water. When many are inside the tank, they will irritate the fish by making sure that they crawl on the fish’s skin and scales. 

The fish get irritated by the presence of mites. The presence of a lot of mites results in damaging a fish’s body. Sooner or later, if the damage exceeds and nothing is done about it, the fish might become prone to the external environment and be unable to survive well in water. 

This will affect the fish population directly, and you wish your timely action could have saved you all the unnecessary trouble. 

How Do Water Mites Enter Acquiriums?

It’s like one day your tank is fine, and the next it’s crawling with mites. It can happen super fast, and when you add the sudden growth of algae, things can really get out of control. I remember this happened to me once when I used a self-feeder before going away for a few days. As the food piled up and stuck to the tank, the mites just multiplied like crazy.

Honestly, I’m not sure how the first mites got in there. I think they might have hitched a ride on some aquarium plants or new fish. Even though all my stuff was new, you could pick up mites from used equipment or decorations that haven’t been cleaned properly. Sometimes it feels like mites just appear out of thin air. There’s no real pattern to it, but generally, they’re more helpful than harmful, unless things go a bit haywire.

How To Get Rid Of Water Mites

1- Raising The Temperature Of the Water

For the water in the pool or aquariums, there is a simple solution for removing the mites. You can increase the temperature to about 86F. A high temperature than usual is enough to kill the mites. 

In the case of the aquarium, you must add a little bit of salt- 1tsp per gallon is required. What does the salt do? It suffocates the mites to death. When the mites die, they float on the water’s surface, and you can easily collect them using a water net. 

If you combine both of these methods, you will obtain the best results. You can heat the water and then dissolve some salt in it. This will ensure that mites are killed due to the heat and suffocation. 

2- Use Of Chlorine

The mites present in water bodies are unwanted. They can quickly become a part of the water from the water plants. The mites are also capable of attaching to aquatic animals like fish. They act as parasites and feed on the body fluids, skin, and scales of the fish they get attached to. 

That is why it is necessary to get rid of mites as soon as possible. You must use bleach and add a little bit to the pool. This will kill the mites. Chlorine is an active agent the bleach. Bleach is a strong and harsh chemical. It would be best if you used it with care. 

Before use, you must dilute it. It can damage the eyes, lungs, and skin of the person. It would be best if you made sure that there is no contact with the skin. Otherwise, it will cause pain to you.

Using chlorine is one of the best options that you have; however, you must handle it and use it with care. 

3- Regular Cleaning And Replacement Water

The best way is to get rid of the previous water and replace it with the new one. This way, you can get rid of the dirty water and all the pests in it. The freshwater will be pest free, and you can have the best clean water for your fish and swimming. 

Another advantage of getting rid of old and dirty water is that it will help you eliminate the mites and their eggs. The mite population will be eliminated this way. It will also keep the water clean from other pests.

The population size will remain under check by cleaning the water regularly. A lot of inconveniences can be avoided for the people who own a pool or an aquarium.

4- Removing Lights

It is said that the lights attract a lot of bugs, including mites. The color of the light is essential when it comes to attracting bugs. Lights of shorter wavelengths like green, UV, and blue are pretty visible to the bugs compared to the lights of longer wavelengths of red light, orange or yellow.

In the daytime, you do not need many lights. All you have to do is be cautious about the night lights. If you do not install lights, it will help in keeping the mites away.

The least you can do is opt for installing such lights that do not attract the mites. For that, you have to search the market and experiment on your own.

How To Get Rid Of Mites In The Aquarium?

There are many ways by which you can solve the issue of mites being present in your aquarium. Many people are worried about their fish and what the mites might do to them. This article will provide all the solutions you need to get rid of your problems

  • Getting Rid Of Copepods
  • Reducing The number of powdered foods 
  • Adding predators To The Aquarium
  • Using Chemicals

The aquarium has a lot of small plants in it as well. It is due to this plantation that the aquarium mites make their way into your aquarium and attach themselves to a fish. There is not much you can do about it at this point. 

You can opt for active treatments to keep your fish safe from mites. Following the methods mentioned, your fish can remain free from mite damage. 

 1- Getting Rid Of Copepods

So, how does one get to know that their fish has mites? It can be observed by paying attention to the signs. The scales of the fish start to fall off. There is many fish that are susceptible to mite attacks. 

The mites feed on copepods. The copepods, in turn, feed on the detritus. It would be best if you kept your tank clean at all times. The cleaning should be done once a month at least.

This will help in getting rid of the detritus. When no debris has accumulated, no copepods will be there, and hence no mites will come to feed on them.

2- Reducing The number of powdered foods

The powdered foods attract the mites in the aquariums. Although this food is given to the fish, they can grow normally and breed properly. The mites also feed on this kind of food and start propagating on their own. 

You can replace these powdered food sources with some other sources. You can always choose alternative products such as fish food. This will keep the mites away. Also, you should not add extra to the aquarium but only enough that keeps the fish alive and thriving. 

Any extra food added to the fish tank will only invite the mites to grow manifold. Before long, you will be dealing with something you have not signed up for. 

3- Adding Predators Too The Aquarium

Some small fish like guppies, tetras, rasboras, gouramis, and anabantoids feed on the water mites. Adding these fish to the fish tank as predators will help eliminate the mites’ population. 

Other common predators include the Albino corydoras, catfish, Otocinclus, Mollies, and platyfish. They feed on the mites. This is the most natural method by which the mite population can be kept under check. 

All you have to do is fill your fish tank with fish that can feed on mites. This way, your aquarium can be filled with fish, and you’ll have the perfect predators to keep the mites away. No other cleaning strategies are required in this case. 

4- Using Chemicals

You cannot possibly opt for the option of using chlorine to kill the mites. In a fish tank, adding chlorine is not a wise option at all. If you have a mite problem getting out of hand, you should take all the fish out first. 

Once the aquarium is empty, you can then add chlorine to it, but the amount should only be a little bit. This will suffocate the mites, and they will die out soon enough. Next, you can replace chlorine water.

In the end, you can fill your tank with fresh water and put back all the fish you took out before doing the treatment of water.
