How to Set Up a Tetras Fish Tank (Starter Guide)

You may have some questions about how to get started and what supplies to buy. Never fear!

Here’s a beginner’s guide on how to set up a neon tetra fish tank with everything you need to ensure the safety and health of your new little friends.

What is the Best Tank Size for Neon Tetras?

Neon tetras are recommended to estimate about 10 gallons (38 L) of water for every 6 neon tetras you want to keep.

This means that if you want to keep 12 neon tetras, you should have an aquarium that holds at least 20 gallons (76 L) of water.

It is also important to note that having too few neon tetras in a tank can also cause problems. If the group is too small, the fish may become stressed, which can lead to illness and death.

How many neon tetras in a 10 gallon tank?

Here’s a table outlining the benefits of keeping different numbers of neon tetras in a 10-gallon tank:

Number of Neon TetrasArea per Fish (Gallons/Liters)Effect of Adding Neon Tetras
61.67/6.34Initial stocking density
71.48/5.61Slight increase in bioload
81.33/5.03Increase in bioload
91.11/4.20Significant increase in bioload
EpicFishTank Note:

It’s important to note that these are just general guidelines and the appropriate number of neon tetras for a 10-gallon tank can vary based on factors such as the overall size and shape of the tank, the presence of other fish or aquatic plants, and the filtration system in place.

#2 Finding the Best Filtration System for Your Tetras

Tetras need clean and healthy water to thrive, so having an effective filtration system is essential. Here are some tips to help you find the right filtration system for your tetra tank.

Consider the size of your tankThe larger the tank, the more powerful your filter needs to be.
Choose the right type of filterHOB filters are great for smaller tanks, while canister filters are ideal for larger tanks.
Look for key featuresFlow rate, noise level, and ease of maintenance are important factors to consider.
Ensure compatibilityMake sure the filter you choose is suitable for your tetras’ needs.

Hang-on-back (HOB) filters are a great choice for small aquariums, like those housing tetras. HOB filters are easy to install and require little maintenance. They can also be customized to fit the size of your tank and the type of fish you have.

The pros of using HOB filters for small tanks include:

  • Easy installation – HOB filters are designed to easily attach to the back wall of most tanks, so you don’t need any special tools or knowledge to set them up.
  • Low maintenance – Once installed, these filters require very little maintenance. You just need to replace the filter media periodically and clean out any debris that accumulates in the filter box.
  • Customizable – You can customize your HOB filter to fit the size of your tank and the type of fish you have, allowing you to get the most out of your filtration system.

The cons of using HOB filters for small tanks include:

  • Not as powerful as other types of filtration systems – While they are effective at filtering water, they may not be as powerful as canister or undergravel filters when it comes to removing waste from your tank.
  • Can be noisy – Depending on the model, some HOB filters can be quite loud when running, which may be annoying if you’re trying to keep a quiet environment in your home.
  • Limited space for filter media – The limited space in a HOB filter means that there is only so much filter media that can be used, which could limit its effectiveness at removing waste from your tank.

#3 Best Substrate for Tetras

The substrate you choose for your tetra tank plays a critical role in creating a healthy and attractive environment for your fish.

💡 The optimal temperature for neon tetras ranges between 72-76°F (22.2 – 24.4°C), and a temperature of 75-76°F (23.9 – 24.4°C) is recommended. Consistency in maintaining the temperature is crucial for the neon tetra’s health and well-being.

Let’s take a closer look at the key benefits of aquasoil compared to other substrate types.

  1. Aquasoil is a specialized aquarium substrate made from natural materials such as volcanic ash and clay.
  2. It’s considered the best substrate for a tetra tank because it provides a variety of benefits for both the fish and the plants in the tank.
  3. Because aquasoil has a dark, natural color that complements the appearance of many tetra species. This can help to create a more natural-looking environment and enhance the beauty of your tetra fish.

#4 Decorate the tank

If you’re a beginner looking to set up a tank for tetras, there are a few key tips to keep in mind. Here are some beginner tips for keeping tetras happy and healthy:

Include plenty of vegetationTetras typically prefer bottom-planted tanks, so aim to include plenty of vegetation in your aquarium. Good plant options include Java Moss, Java Fern, Vallisneria, Amazon Sword, and Anubias Petite.

These plants not only provide hiding places for your tetras but also improve water quality by absorbing excess nutrients and producing oxygen through photosynthesis.
Add floating plantsConsider adding floating plants to your tank to ensure that your tetras get the right amount of light. Some good options include Frogbit, Duckweed, and Brazilian Pennywort.

Water lettuce is a good choice because it provides a mat of plant life at the top of the tank while still allowing enough light to reach the plants at the bottom. However, it’s important to remove floating plants if they start to block too much light.

#5 Get the perfect heater for your tetras

💡 The optimal temperature for neon tetras ranges between 72-76°F (22.2 – 24.4°C), and a temperature of 75-76°F (23.9 – 24.4°C) is recommended. Consistency in maintaining the temperature is crucial for the neon tetra’s health and well-being.

Here’s a table summarizing the tips for choosing a heater for tetras:

Determine the size of your tankThe size of your tank will determine the size of the heater you need. Check the recommended tank size listed on the packaging.
Choose the right wattageUse the general rule of about 5 watts of heating power per gallon of water in your tank. For example, a 10-gallon tank will need a heater with at least 50 watts of heating power.
Consider the temperature rangeMost tetras prefer water temperatures between 72 and 82 degrees Fahrenheit. Choose a heater that can maintain this temperature range.
Look for a reliable brandChoose a heater from a reliable brand that has good reviews and a track record of producing high-quality products.
Consider safety featuresLook for a heater with safety features such as automatic shut-off and overheat protection. These features can help prevent accidents and ensure the safety of your fish.

By following these tips, you can choose a heater that is appropriate for your tetras and keeps them happy and healthy.

#6 Choose the Right Lighting for Your Tetras’ Aquarium

To make sure your aquarium’s lighting is providing the necessary requirements, there are a few key considerations to keep in mind.

In this table, we have summarized the important factors you need to consider when selecting lighting for your tetras’ aquarium

ConsiderationsKey Points
WattageNeon tetras require 2-5 watts per gallon of water in a well-planted aquarium. For example, a 10-gallon tank requires a light with at least 20-50 watts of power.
Type of LightingLED lights are popular for aquariums as they provide bright and vibrant light without generating too much heat, and come in various colors.
Daily Light DurationMost experts recommend 12-14 hours of light per day for tropical fish like tetras. Set up an automatic timer or switch if necessary.

How to Take Care of a Neon Tetras

Here are some tips on how to take care of your neon tetras so they stay happy and healthy!

How To Introduce a School of Tetras to Their New Home

By following these tips, you can make sure your tetras feel like VIP guests at their new home, and they’ll swim away happy and healthy!

Acclimate your tetrasBefore you introduce your tetras to their new home, it’s important to help them adjust to the water conditions.
