Do Tetras Eat Plants?

Did you know that tetras are omnivorous, and they eat plants too? However, they are more interested in dead or decaying plant matter and algae. Algae can provide essential minerals and nutrients for your tetras, but don’t rely on them to keep the algae population under control.

Do Tetras Eat Plants? No. Tetra does not eat fish plants, but they eat small algae growth on fish plants. Even if they eat small fish plants under any condition, it will be uncountable and not harm your fish plants.

Do Tetras Eat Plants

Algae grow faster than your tetras’ appetite, so you still need to do regular maintenance to prevent it from spreading too much. Algae can also take away oxygen and nutrients from the water, so you need to be careful.

Unlike goldfish, tetras usually don’t eat live fish plants, so you don’t have to worry about them munching on your aquarium plants. Just make sure you feed them properly.

If your tetras don’t get enough essential minerals from their diet, they might nibble on some plants. But don’t worry. Tetras don’t usually eat live plants as much as other fish do, so your plants won’t get hurt that much.

To avoid that, make sure your tetras have a balanced diet that includes enough vegetables. Please give them a variety of food to keep them happy and healthy.

Live or Frozen feed

Did you know that tetras in the wild eat a lot of live food to stay healthy and live long lives? Well, domesticated aquarium tetras are no different. And lucky for us, there are two options when it comes to feeding them live or frozen food.

The first option is to set up a live food culture for your tetras. This might be the best option if you’re really committed to providing your fish with the freshest, most nutritious diet possible.

You can get kits online to help you set up your own live food culture, which can provide your tetras with a consistent source of fresh food.

Some popular options for live food cultures include shrimp, bloodworms, daphnia, and vinegar eels. Each type of culture has its own requirements, so make sure to do your research before diving in.

Frozen food is a convenient option for feeding your tetras. You can either buy them pre-made from the store or make them yourself at home. The advantage of making your own is that you can control the ingredients and avoid any artificial additives.

To make your own frozen food, you can start by mixing live food with vegetables to create a nutritious paste. Once the paste is ready, freeze it and then portion it out to feed your tetras throughout the week. This way, you’ll have a steady supply of food that you can replenish as needed.

Homemade tetra fish food

Let’s talk about homemade food for your tetras. It’s an exciting topic because there are so many options and opportunities to explore. Basically, homemade food means making a protein paste using various food items.

A typical protein paste will contain ingredients like egg yolk, beef heart, shrimp, white fish meat, veggies, and more. Just be sure to pay attention to the fat content since adult tetras don’t tolerate foods that are too high in fat.

The best part about homemade food is that you can personalize it with whatever ingredients you like. Once you’ve made the veggie paste, you can freeze it and use it for several days, which is a real-time-saver while still providing your tetras with nutritious food.

Blanched Vegetables for tetras

When it comes to feeding your tetras, vegetables are a great addition to their diet. There are so many veggies to choose from, so the key is to offer a diverse range to ensure your tetras get all the vitamins and minerals they need.

You don’t need to cook the veggies for too long, as boiling them for a few minutes should suffice. Some examples of veggies that tetras can eat include,

  • Carrots
  • Cucumbers
  • Bell peppers
  • Potatoes
  • Tomatoes
  • Spinach
  • Sweet corn
  • Peas

If you want to mix things up, you can even boil the veggies and blend them into a nutritious paste along with shrimp, fish, or bloodworms. This is a great way to provide your tetras with a variety of nutrients.

Remember that tetras tend to overeat, which can be harmful to their health and even pollute the tank water. To prevent this, only feed them once or twice a day, or even once every other day, depending on their preferences and habits.

Aquarium Plants For Tetras

Choosing the right plants for your tetra tank is crucial for maintaining a healthy and vibrant environment for your fish. There are several factors to consider when making your selection, such as the plant’s ability to consume ammonia and increase oxygen levels, as well as the plant’s growth pattern.

Aquarium Plants For Tetras

Certain plants, for instance, will spread throughout the tank, providing hiding spots for your tetras.

However, they may also block light, which can be detrimental to the growth of other plants in the tank. Other plants may not grow as quickly, but they can help to oxygenate the water and remove harmful toxins.

Here are some of the most popular plants to use in your tetra tank

  1. Java Moss
  2. Amazon Sword
  3. Water Wisteria
  4. Hornwort
  5. Anubias Nana
  6. Java Fern
  7. Cryptocoryne Wendtii
  8. Dwarf Baby Tears
  9. Marimo Moss Balls

Each of these plants has its unique characteristics and can contribute to the health and well-being of your tetras in various ways. However, it’s essential to research each plant’s specific needs and requirements before adding them to your tank to ensure they thrive.


So, you might be wondering if your tetras will chow down on all the plants in your aquarium. Well, the good news is that as long as you’re giving them a healthy and balanced diet, they probably won’t be too interested in snacking on the plants.

However, it’s essential to keep in mind that tetras aren’t the best at keeping your tank algae-free. Even if they do nibble on some of it, it won’t be enough to keep up with the rapid growth of algae in your tank.

So, make sure to give your tetras a mix of live food and veggies to keep them satisfied and minimize their interest in the plants.
