What Kind Of Plants And Decorations Does Tetra Fish Like? – Artificial(Plastic) Aquarium Plants

Besides the live bottom and floating/cover plants, plastic aquatic plants can’t go wrong either. Firstly, let me be clear. Go for the use of plastic aquatic plants if you’re an experienced fish hobbyist. Don’t jump directly into plastic plants if you’re a beginner.

Pros Of Artificial(Plastic) Aquarium Plants

Nevertheless, there are various benefits of using plastic plants in your aquarium. Not being the live plants, you need not bother about the water parameters for the plastic plants.

Moreover, the cleaning of plastic plants is easy. You just need to take out the plants and rub/ scrub off with a brush, algae pad or spray with the showerhead.

You don’t have to fear for the plants to die either. You should not add additional substrates for the plastic plants too. These plants don’t require fertilizers, lighting, or even CO2. Isn’t it great?

Cons Of Artificial(Plastic) Aquarium Plants

Setting up an artificial plastic aquarium isn’t as hard as setting the live aquarium is. Although, as I said earlier, beginners must not go for it.

One should have experience with the live plants’ aquarium too. It’s because some plastic plants might harm your sensitive fish like Tetra.

As simple as it is, plastic plants don’t absorb carbon dioxide and nitrates nor provide oxygen to the fish.

Additionally, Tetra fish love to eat algae too, and artificial plants don’t allow and support the growth of Tetra. In other words, artificial plants don’t have any biological value for the fish aquarium.

 Keep The Plants Healthy

After you set up your tank from all the plants, you shouldn’t forget to keep them healthy too.

Cleaning won’t be hard if you’ve artificial plants. But, keeping the live plants won’t be a problem if you’ve live plants.

However, I’m not trying to scare you. You must analyze the nature of the plants that you keep. Then, you need to maintain the plants as per their requirement.

Change And Remove The Plants If Necessary

The main task after keeping the plants is to maintain them. As every plant have their nature, you must change and remove the plants too.

Some plants need extra care, while some might not. Change and remove the decayed or dead plants on time to decrease the chances of an increase in wastage.

Fertilize The Plants

Proper Fertilization of the live plants is an essential factor in an aquarium. It’s because the plants and the fish are bound in a limited space.

When Tetras produce excess waste, you must change the water every once in a while. But what about the plants?

Yes, the live plants will help to clear up the dirty environment by observing either nitrogen, nitrites, and carbon dioxides. However, you must not forget that the plants need the required level of care too.

Although there are plants that will live for too long and don’t require much care, you must still not be careless.

Various plants require some level of care, as well. There are fertilizers available in the market for such plants. But let me warn you.

One fertilizer may not be suitable for every plant and fish that you keep. Check the name and brand of the fertilizer and the uses of it before buying one.

What Plants Should You Avoid For The Tetra Fish?

You know about what kind of plants and decorations does Tetra fish likes. So, you must also know about the plants you should avoid.

Some Tetras may just love to eat some sort of plants. You may not like it if you have spent a fair amount of your time to cultivate those plants, isn’t it?

Not only that, you wouldn’t love to hear that some plants may even hurt your fish. Those plants may die and even lead your fish to stress out.

Even though the bright and vibrant foliage may add interest and appeal to your tank, it may not be the best choice for Tetras.

Furthermore, emerged water plants are also not suitable for Tetras in an aquarium. The water parameters and their nature may not match.

Whenever you think of buying a specific plant, you must check the details of it. Every plant is different from each other. While some may be useful for the Tetras, some might be harmful too.

Will Too Many Plants Kill The Tetra Fish?

Well, anything more than necessary is harmful to everyone or anything in the world. That’s the reason why you should balance the number of plants for the Tetras too.

Being sensitive being, these fish prefer living in a comfortable environment. Yes, mimicking the natural environment of the Tetras is essential. However, it doesn’t mean that you’ll add too many plants to the aquarium.

So yes, keeping too many plants in the aquarium will stress or even kill the Tetra fish. Just keep enough plants to balance the water temperature and to provide enough vegetation to the Tetras.

Decoration And Substrates

We are continuing to talk about what kind of plants and decorations does Tetra fish likes. You already know about the Aquarium Plants For Tetra Fish, we’ve now reached the part of decoration and substrate.

Besides plants, Decoration and Substrates also plays a vital role for the Tetras, especially in captivity.

Keeping the right decoration and substrates will make the Tetras happy and stress-free. However, the wrong ones might do the opposite. So, be careful. Choose the ones which will mimic the real environment of the Tetras.

Lots Of Hiding Places

Tetras, being peaceful and shy fish, will love to hide a lot behind suitable areas. Not only that, but Tetras hide when they feel insecure and uncomfortable too.

Tetras get scared easily from the fish species larger than them, and hiding is the option they choose.

Tetras are sensitive beings just like we are, and these fish might get sick often as well. So, Tetras require lots of hiding places.

Some of the best substrates for hiding are rocks, gravel, driftwood, caves, etc. The darker ones, which will make the tank to be naturally darker, are the best suitable options.

Swimming Space

If you didn’t know, Tetras love to swim around the tank. Some are fast swimmers. All you have to do is to ensure that they have enough space to swim around comfortably.

Like the fish experts have said, per-inch of fish require one-gallon of water. Even if you keep the number of Tetras according to the size of your tank, it’s essential to give them adequate space.

Tetras will stress out fast if they don’t get the space they require. Leave some extra space after you keep the plants and substrates as well.

Lighting, Heating, And Filtration

Other vital parts for both the plants and the Tetra fish are lighting, heating, and filtration. You already know that the Tetras don’t prefer bright lighting.

So, you’ll choose the best suitable plants which don’t require bright lighting as well. Bright lighting may harm both the fish and the plants.

Moreover, heating is another essential part of plants and fish. Some plants and Tetras have a similar choice in the water temperature.

Thus, keep a water heater to balance the water parameters so that it doesn’t affect them.

Lastly, proper filtration is the most crucial thing for the fish, especially in captivity. The plants may help to reduce some level of excessive wastage.

But, it’ll not be enough as the waste won’t have a way of its own to leave the aquarium. So, keeping a proper filtration system is necessary to keep the tank clean and healthy.

Conclusion- Plants and Decorations For Tetra Fish

Now that we’ve reached the end of this article, you know what kind of plants and decorations does the Tetra fish like, don’t you? Well, choosing the exact plant which Tetra likes may be a little difficult task. But since there are too many options available, I guess it may not be too difficult as you think.
