Do you have a Flowerhorn Fish in your aquarium? If so, you may have noticed that flowerhorn fish often brush up against the plants. You might be worrying if they are sick or scared. There are several reasons why this may be happening, and we will explore them in this blog post.
One possibility is that there is a high concentration of metals in the water. This can happen when the aquarium is not properly cycled. Another reason for the behavior may be parasites. Fluctuating pH levels and temperature can also cause fish to scratch themselves on the substrate.
In some cases, it is nothing to worry about – but in others, it may be a sign that something is wrong. We will discuss all of these possibilities and more!
Why do Flowerhorn Fish Brush Up Against Plants in an Aquarium?
There are a few possible reasons why your flowerhorn fish might be brushing up against plants in their aquarium. It could be that there is a high concentration of metals in the water, that they have parasites, or that the aquarium isn’t properly cycled. Another possibility is that the pH levels and temperature are fluctuating.
There May Be a High Concentration of Metals in the Water
One reason your flowerhorn fish might be brushing up against plants is that there is a high concentration of metals in the water. This can happen if you’re using tap water that contains high levels of copper or other metals. You can test the levels of metals in your water with a simple test kit from the pet store.
If the levels of metals are high, you’ll need to do a water change and use a water filter that removes metals. You can also add plants to your aquarium that will help absorb metals from the water.
Your Flowerhorn Fish May Have Parasites
Another possibility is that your flowerhorn fish has parasites. These tiny creatures can attach themselves to the fish’s skin and cause irritation. If you suspect that your fish has parasites, take them to the vet for a check-up.
The parasites that your flowerhorn can suffer from are :
- Anchor worms
- Flukes
- Ich
- Velvet
To treat your fish, the vet will likely give them a medication that you’ll need to add to the water. They may also recommend adding plants to the aquarium that will help absorb the parasites.
Ich In Your Flowerhorn
Ich is the most common parasite that affects fish, and it can be treated with a medication called copper sulfate.
This parasite is caused by a single-celled organism that attaches to the fish’s skin and causes irritation. The parasite can also cause the fish to scratch themselves on plants or other objects in the aquarium.
If you suspect that your flowerhorn has ich, take them to the vet for a check-up. The vet will likely prescribe a medication that you’ll need to add to the water.
The symptoms can be :
- White spots on the fish’s skin
- The fish scratching themselves on objects in the aquarium
- The fish rubbing their body against plants or other objects in the aquarium
Treatment
To treat ich, the vet will likely prescribe a medication that you’ll need to add to the water. The most common medication is copper sulfate.
You’ll need to follow the directions on the package and carefully monitor the levels of copper in the water. Too much copper can be harmful to your fish.
Flukes In Flowerhorn
Flukes are another type of parasite that can affect your flowerhorn. These parasites attach themselves to the fish’s skin and gills and cause irritation.
If you suspect that your flowerhorn has flukes, take them to the vet for a check-up. The vet will likely prescribe a medication that you’ll need to add to the water.
The symptoms can be :
- Eyespots in the flowerhorn
- The fish scratching themselves on objects in the aquarium
- The fish rubbing their body against plants or other objects in the aquarium
Treatment
To treat flukes, the vet will likely prescribe a medication that you’ll need to add to the water. The most common medication is copper sulfate.
You’ll need to follow the directions on the package and carefully monitor the levels of copper in the water. Too much copper can be harmful to your fish.
Anchor Worms In Flowerhorn
Anchor worms are another type of parasite that can affect your flowerhorn. These parasites attach themselves to the fish’s skin and cause irritation.
Your Aquarium is Not Properly Cycled
If your aquarium isn’t properly cycled, it could be another reason why your flowerhorn is brushing up against plants. When an aquarium isn’t properly cycled, it means that there aren’t enough beneficial bacteria in the water to break down waste. This can cause ammonia and nitrites to build up in the water, which can be toxic to fish.
You can test the levels of ammonia and nitrites in your water with a simple test kit from the pet store. If the levels are high, you’ll need to do a water change and add more beneficial bacteria to the water. This can be done with a product from the pet store or by adding live plants to the aquarium.
Fluctuating pH Levels and Temperature
Another possibility is that the pH levels and temperature in your aquarium are fluctuating. Fish are very sensitive to changes in their environment, so even small fluctuations can cause stress. This can lead to fish scratching themselves on plants or other objects in the aquarium.
If you suspect that this is the case, make sure to test the water regularly and take steps to stabilize the pH and temperature.
When Scratching is Not a Cause for Concern
Sometimes fish will scratch themselves on plants or other objects in their aquarium simply because they are itchy. Fish can get itchy for a variety of reasons, including allergies, parasites, and even dry skin. If your fish is scratching itself but otherwise appears healthy, there’s no need to worry. However, if the scratching is excessive or accompanied by other symptoms, it’s best to consult a veterinarian.
Your Fish Scratches Itself on Substrate
If your fish is mainly scratching itself on the substrate ( gravel, sand, etc.), it could be a sign that the substrate is too rough. Fish can get scratches and other wounds from the sharp substrate, so it’s important to use a soft, sandy substrate in your aquarium.
You can also add plants to your aquarium that will help soften the substrate and provide a place for your fish to hide if they’re feeling stressed. Here are two soft substrates you can use for your flowerhorn:
- Carib Sea ACS05820 Super Natural Moonlight Sand for Aquarium, 5-Pound
- Carib Sea ACS05840 Super Naturals Crystal River Sand for Aquarium, 5-Pound
The Flashing is Not Consistent
Another reason your fish might be flashing is that the water quality in their tank isn’t good. Ammonia and nitrites can build up in an uncycled tank, which can be toxic to fish. If you notice that your fish are flashing more often than usual, take a water sample to the pet store for testing.
If the levels of ammonia or nitrites are high, you’ll need to do a water change and add more beneficial bacteria to the tank. This can be done with a product from the pet store or by adding live plants to the aquarium.
Remove Sharp Objects from Your Aquarium
If your fish is scratching itself on objects in the aquarium, make sure that those objects are not sharp. Fish can easily get cuts and other wounds from sharp objects, so it’s important to remove any rocks or other decorations that could hurt them.
You can also add plants to your aquarium that will provide a softer place for your fish to scratch themselves without getting hurt.
