Ember Tetras…How Hardy Are They?

Ember tetras (Hyphessobrycon amandae) are considered relatively hardy fish, making them a good choice for beginner aquarists.

They can adapt to a broader range of water parameters than some other tetras. However, there are a few things to keep in mind:

  • Aquacultured vs. Wild-Caught: Ember tetras bred in captivity (aquacultured) are generally hardier than wild-caught specimens. This is because they are already adapted to aquarium conditions.
  • Water Conditions: Ideally, ember tetras prefer soft, slightly acidic water (pH 5.5-7.5) with a temperature range of 72-82°F (22-28°C). However, they can tolerate a wider range of water parameters as long as the changes are gradual.

The key to success when keeping ember tetras is understanding their behavior as schooling fish. According to the care guide, ember tetras should be kept in groups of at least 6-8 to thrive and display their natural behavior.

These colorful fish, with their red-orange bodies, are a smaller tetra species, reaching only about 1 inch in size. When setting up a tank for ember tetras, a freshwater Nano basin of at least 10 gallons is recommended.

To make them feel secure, provide plenty of hiding spots among aquatic plants and Java moss. Consider adding a sponge filter to maintain water quality and a balanced diet, including daphnia, microworms, and plant matter. To keep them healthy, avoid overfeeding and ensure they are properly acclimated to their new environment through drip acclimation.

For those looking to add more variety to their tank, ember tetras can coexist peacefully with other small and peaceful fish, such as dwarf cichlids, Corydoras catfish, and Otocinclus catfish.

Avoid pairing them with larger fish or aggressive species like bettas or barbs, as ember tetras are timid and may become stressed. Providing a natural habitat with soft, slightly acidic water mimicking their native environment will help them thrive.

Additionally, adding floating plants and algae can provide them more natural grazing opportunities. Consider adding black neon tetras or neon tetras to the tank to enhance their colors and keep them active. These vibrant species of tetras will contrast beautifully with the ember tetras and make the tank even brighter.

Tetras Behavior & Temperament

Tetras are known for their peaceful behavior and are great for community tanks. They prefer to be in a shoal, so keeping them in groups of at least six is essential. They are adaptable to various tank sizes and water conditions but do best in a tank with hard water.

Their lifespan ranges from 3 to 5 years, making them a long-term commitment for fish enthusiasts. They are small, making them easy to care for and suitable tankmates with other fish, such as betta fish and dwarf Gouramis. It’s essential to have a variety of plants and hiding spots in the tank, as they like to explore the entire bottom of the tank.

It’s important to note that male tetras can sometimes be aggressive towards other males, so it’s best to have a good ratio of males and females in the tank. Proper LFS (Local Fish Store) knowledge will help ensure a harmonious community tank. Tetras are generally hardy fish but prone to specific health problems if not kept in optimal conditions.

With their vibrant colors and active behavior, tetras make great centerpieces in any aquarium. They are also easy to care for and make great additions to any community tank, making them ideal choices for both beginner and experienced fishkeepers.

What To Put In Their Tank

When deciding what to put in their tank, it is essential to consider the small size of the space. Small-size tanks are best suited for fish that do not require a lot of swimming room.

Opt for smaller species, such as bettas, guppies, or tetras, which thrive in a smaller environment. Consider adding live plants to provide oxygen and a natural habitat for your aquatic friends.

It’s also important to regularly clean and maintain the tank to ensure a healthy environment for the fish. By carefully selecting the proper inhabitants and keeping up with maintenance, you can create a thriving ecosystem in your small tank.

How to Set Up an Aquarium for Ember Tetras

Setting up an aquarium for Ember Tetras requires careful consideration to ensure the health and well-being of these vibrant fish. Firstly, choose a tank size of at least 10 gallons to provide enough space for a small school of Ember Tetras.

Next, a heater should be set up to maintain a temperature between 74-82°F, as these fish prefer warmer water. Use a gentle filter to provide a steady flow and maintain water quality. Decorate the tank with live plants and driftwood to mimic their natural habitat and provide hiding spots.

Finally, carefully add a small group of Ember Tetras, ideally 6-8 individuals, to the tank to avoid stressing them out. Your Ember Tetras will thrive in their new aquatic environment with proper setup and maintenance.

Can Ember Tetra live without a Filter and Heater?

While Ember Tetras are known for being hardy, keeping them without a filter and heater is not recommended. Here’s why:


  • Water Quality: A filter is crucial for maintaining good water quality in your tank. It removes fish waste, leftover food, and decaying plant matter. Without a filter, these elements can build up and create ammonia and nitrites, which are toxic to fish. Ember Tetras can tolerate some fluctuation, but rapid changes or consistently poor water quality can stress them and make them susceptible to disease.


  • Temperature Regulation: Ember Tetras originate from blackwater streams in South America with a stable temperature range. They thrive in aquariums with a temperature between 72-82°F (22-28°C). An aquarium heater is necessary to maintain this range in more relaxed environments. Without a heater, fluctuating temperatures can stress the fish and weaken their immune system.

Even though Ember Tetras are adaptable, avoiding a filter and heater altogether increases the risk of:
