Ember Tetra Care Guide: Tank Setup and Maintenance

Ember tetras (Hyphessobrycon amandae) are captivating little fish that add a burst of color and vitality to your home aquarium. In this comprehensive care guide, we will delve into the essential aspects of keeping Ember tetras healthy and happy in your tank. From the appropriate tank size to water temperature, pH levels, and troubleshooting issues like color loss, we’ve got you covered.

Ember Tetra Tank Size

The Ember tetra is a small fish, making tank size a critical factor in their well-being. A larger tank provides more stable water conditions and allows these fish to display their natural behaviors. The minimum tank size recommended for Ember tetras is 10 gallons. However, if you plan to keep a small school of them, consider a 20-gallon tank to provide ample swimming space and accommodate their social nature.

Ember Tetra Tank Size Requirements

Selecting the appropriate tank size is a fundamental aspect of caring for Ember tetras (Hyphessobrycon amandae). These small but vibrant fish have specific requirements that must be met to ensure their well-being and happiness in captivity. Let’s delve deeper into the importance of tank size and explore the reasons behind the recommended minimum tank size of 10 gallons.

Understanding Ember Tetra’s Natural Habitat

To determine the ideal tank size for Ember tetras, it’s essential to consider their natural habitat. These charming fish originate from the slow-moving waters of the Araguaia River basin in Brazil. In their native environment, Ember tetras thrive in densely vegetated areas, where they find refuge among aquatic plants, driftwood, and submerged roots.

The relatively small and gentle flow of their native waters has influenced their behavior and preferences. They are accustomed to living in schools, darting among plants, and seeking shelter when needed. This natural behavior should be replicated as closely as possible in their aquarium environment to keep them stress-free and encourage their vibrant coloration.

Why a 10-Gallon Tank?

The recommended minimum tank size of 10 gallons for Ember tetras serves several essential purposes:

1. Swimming Space

While Ember tetras are small, they are also active swimmers and social fish. Inadequate space can lead to stress and limit their ability to express natural behaviors, such as shoaling and exploring. A 10-gallon tank provides enough room for a small school of Ember tetras to swim comfortably and interact with each other.

2. Water Stability

A larger tank generally offers greater stability in terms of water conditions. Smaller tanks can experience rapid fluctuations in temperature and water quality, which can be detrimental to sensitive fish like Ember tetras. The larger water volume in a 10-gallon tank helps maintain more consistent parameters.

3. Planting Opportunities

Ember tetras feel most at home in a well-planted aquarium. A 10-gallon tank provides sufficient space for a variety of live or silk plants, rocks, and driftwood. This allows you to recreate the lush, plant-filled environment of their native habitat, offering hiding places and natural foraging opportunities.

4. Compatibility

A 10-gallon tank provides enough space to consider compatible tank mates. Ember tetras are generally peaceful but can be intimidated by larger or more aggressive fish. The additional room allows for a harmonious community of fish, provided they share similar water parameter requirements.

Larger Tanks for More Ember Tetras

While 10 gallons is the minimum tank size for Ember tetras, if you have the space and inclination, consider a larger tank. A 20-gallon tank, for example, offers even more swimming space and allows you to keep a more extensive school of Ember tetras. In a larger tank, these charming fish can showcase their natural behavior and vibrant colors to the fullest extent.

Remember that the key to a successful Ember tetra aquarium is not just the size of the tank but also the attention to detail in replicating their natural habitat. Adequate hiding spots, proper filtration, appropriate lighting, and maintaining stable water parameters are equally crucial to ensure the health and happiness of your Ember tetras.

Substrate and Decorations

Ember tetras hail from the slow-moving waters of Brazil, so it’s best to replicate their natural habitat. Use fine gravel or sand as the substrate, mimicking the soft riverbed. Incorporate driftwood, rocks, and live or silk plants to create hiding spots and provide a visually appealing environment.

Filtration and Water Flow

A good-quality aquarium filter is essential to maintain water clarity and quality. Since Ember tetras prefer calm waters, choose a filter with adjustable flow settings to avoid excessive water movement. Additionally, consider placing some floating plants to diffuse light and provide shade.


These tetras thrive in well-lit environments with moderate to low lighting. Use LED aquarium lights on a timer to simulate natural day-night cycles. Avoid intense lighting to prevent stress and excessive algae growth.

Water Parameters

Ember tetras are sensitive to water conditions, so maintaining stable parameters is crucial:

  • Water Temperature: Keep the temperature between 74°F to 80°F (23°C to 27°C) to mimic their native warm waters.
  • pH Level: Maintain a slightly acidic to neutral pH of 6.0 to 7.0.
  • Water Hardness: Aim for soft to moderately hard water with a dGH (degrees of general hardness) of 5-12.

Regularly monitor these parameters with a reliable test kit and perform water changes of 20% every two weeks to keep them within the recommended range.

Ember Tetra Seriously Fish

When sourcing Ember tetras for your aquarium, it’s essential to choose healthy specimens. Reputable fish stores and online retailers often provide Ember tetras sourced from well-established breeders. Always ask for information about the fish’s origin, and if possible, check their compatibility with other tank mates.

Ember Tetra Color

One of the most alluring features of Ember tetras is their vibrant coloration. Their bodies shimmer with shades of red and orange, resembling the embers of a fire. To ensure your Ember tetras maintain their stunning color, pay attention to their diet and environment:


A well-balanced diet is the key to vibrant coloration in Ember tetras. Offer them a combination of high-quality flake food, micro pellets, and live or frozen foods like daphnia and brine shrimp. These foods provide essential nutrients and pigments that enhance their colors.

Water Quality

Maintaining pristine water quality is directly linked to the vibrancy of their colors. Regular water changes, proper filtration, and monitoring ammonia and nitrite levels are vital to keeping their environment pristine.

Ember Tetra Losing Color

If you notice your Ember tetras losing color, it could be due to several factors:

  1. Stress: Ensure that tank mates are not harassing them. Providing adequate hiding spots and maintaining stable water conditions can alleviate stress.
  2. Poor Diet: Evaluate their diet and make sure they are receiving a balanced and varied menu. Adjust feeding habits if necessary.
  3. Water Quality: Check water parameters and perform a water change if needed. High ammonia or nitrite levels can lead to color loss.
  4. Aging: As Ember tetras age, their colors may fade naturally. This is a part of their lifecycle.

Ember Tetra Parameters
