Do Fish Get Itchy?
The answer is Yes. Like dogs, cats, or humans, fish can also get itchy. It is also known as “flashing” in fish.
Fish do not have paws or hands. As a result, if something irritates their skin, they will rub past anything scratchy, such as a plant leaf or rock, to handle it.
One of the most common signs is that your fish accelerate suddenly to your aquarium’s bottom or side to rub its side. Swimming in sudden bursts and twitchy swimming are also noticeable signs.
Some even jump out of the water to take advantage of the water’s surface tension to solve the itch. So, it can be dangerous if your fish jump out of the aquarium.
Common Causes of Flashing in Fish
A parasitic infestation is one of the most common causes of your fish itching. Here are some common aquarium parasites that may make your fish flash:
- Protozoa Trichodina
- Costia (or Ichthyobodo)
- Monogenean trematodes (or flukes)
- Ichthyophthirius
- Chilodonella
- And more
These parasites are usually microscopic, and you will need the help of a trusted veterinarian to diagnose the parasites and handle them.
Parasitic infections often occur when you add new mates or plants that have not been appropriately quarantined.
Moreover, outbreaks may occur in your fish due to a chronic stress situation, like your tank being overcrowded or the water being low quality.
Wild fish have low levels of parasites in most cases. It is because their immune system can control parasites thanks to their aquatic habitat’s nature.
But when chronic stress situations occur, their immune system will weaken, enabling the proliferation of bacteria and parasites.
Temperature also plays a vital role in the speed of a parasite outbreak.
Specifically, the warmer the water, the faster the parasite’s life cycle, making the outbreak more advanced.

How Do I Stop My Fish From Itching?
Diagnostic Process
The best way to determine the cause of your fish’s itching is to get help from your veterinarian.
Your vet will check out the number of fish, aquarium size, and filtration system. He will also analyze the water quality in your aquarium and inspect your fish.
Your veterinarian can then offer advice on reducing the biological load or reducing the number of individuals in your aquarium.
You can also get advice on tank improvements and maintenance procedures before starting to raise fish.
When taking a physical exam for your fish, your vet will take tiny gill and skin mucus samples.
Afterward, he will evaluate those biopsy samples under his microscope to determine if a parasite outbreak occurred.

Treatment Process
The treatment process depends on scratching the parasite irritating your fish. No treatment is best for all cases and is guaranteed to work for all types of fish.
There are many options for treatment, and you will need to make a choice based on several factors, including:
- The fish in your aquarium
- Medicines that you have put in your aquarium
- The severity of the parasite outbreak
- The condition of your sick fish.
Some methods may focus on dealing with primary stressors, such as an overcrowded aquarium or poor water quality, rather than treating parasites.
For mild outbreaks, once you’ve dealt with the main stressors, you can expect your fish to handle the infection themself.
How Can You Prevent Itching in Your Fish?
When discussing preventing a parasite outbreak in your aquarium, we recommend putting all new plants and fish in another aquarium for four to six weeks before placing them in your main tank.
Thanks to that, you can isolate potentially sick individuals to prevent spreading diseases, including bacteria, viruses, and parasites, from entering your healthy aquatic community.
If your new fish is sick, you can also quickly treat them during quarantine.
Let’s say you only see your fish “flashing” occasionally. In this case, you won’t need to worry if no live plants or new fish have joined your aquarium in the past three months, the water quality is not bad, and you are maintaining a good diet.
Sometimes, your fish get itchy due to skin irritation or small amounts of parasites, which they can handle themself.
However, if “flashing” in your fish is more frequent, you should treat it before it becomes more serious.
