Hyphessobrycon amandae, commonly known as Ember Tetras, are a popular freshwater aquarium fish.
They are native to the Amazon River basin in South America.
Ember Tetras are relatively small, reaching a maximum length of about 2.5 cm.
They are a peaceful and schooling fish that thrive in the company of their own kind, so keeping them in a group is essential.
In the wild, Ember Tetras inhabit slow-moving waters with dense vegetation, where they feed on small invertebrates and plankton.

Water Conditions
To keep your hyphessobrycon amandae healthy, you'll want to get their water conditions just right. Temperature-wise, you're looking at a range of 20 – 28 °C, which is perfect for these fish.
A slightly acidic to neutral pH is also key, falling between 5.0 – 7.0. This will help them thrive in their environment.
Water hardness is another important factor, with a range of 18 – 179 ppm. This will ensure your fish are getting the nutrients they need to stay healthy.

Care and Housing
To keep your Hyphessobrycon amandae (Ember Tetras) happy and healthy, you'll want to provide them with a suitable environment. A 20-liter aquarium is sufficient for breeding, but a 5-gallon nano tank is a good size for a regular setup.
The water should be slightly acidic to neutral, with a pH between 5.0 and 7.0. A temperature range of 26-28°C is ideal for these fish. To reduce stress and create a natural environment, keep the aquarium very dimly lit.
For filtration, use an air-driven sponge filter or air stone to ensure adequate oxygen and light water movement. This will also help to create a gentle flow that these fish prefer.

Setting Up an Aquarium for Tetras
Tetras are incredibly social creatures that thrive in the company of their own kind, so it's essential to keep them in a group. For a nano tank, a minimum of 6-10 tetras is recommended to create a visually appealing and engaging environment.
A 5-gallon nano tank is a great option for keeping tetras, but you can also opt for a larger tank if you prefer. The key is to provide a spacious environment that allows them to swim and thrive.
Tetras are adaptable to a pH range of 5.5-7.5 and temperatures between 72-82°F (22-28°C), making them a great choice for hobbyists with varying water conditions. However, they do prefer very soft to moderately hard water.
Slow flow with gentle filtration is preferred, and a sponge filter or pre-filter sponge is a great option. In fact, we find that ember tetras tend to show brighter colors in planted tanks with a dark substrate and background.
To create a more natural environment, consider adding catappa leaves, driftwood, and other interesting botanicals. This will not only provide visual interest but also create hiding places and visual barriers for your tetras.
In terms of tankmates, tetras are generally peaceful and can be kept with other nano schooling fish, such as rasboras, tetras, and danios. They also get along well with bottom-dwelling corydoras catfish and surface-dwelling hatchetfish or pencilfish.

Tetras' Diet
Ember tetras are omnivores that enjoy eating zooplankton, small invertebrates, and plant matter.
They have little mouths that prefer to feed on tiny, slow-sinking foods.
Feeding a varied diet of different fish foods will help them get plenty of essential nutrients and vitamins to live a long and healthy life.
Some of our favorite foods for ember tetras include:
- Nano pellets
- Crushed flakes
- Baby brine shrimp
- Easy Fry and Small Fish Food
- Daphnia
- Cyclops
- Rotifers
Natural Habitat
Ember Tetras thrive in rivers, lakes, and streams with slow-moving currents. This environment is characterized by branches, fallen logs, and abundant leaf litter.
Their natural habitat is enriched with tannins, resulting in a dark, nearly black appearance, often referred to as "blackwater." This unique condition is a result of the water's acidity.
In their native habitat, Ember Tetras find ample shade and shelter among lush vegetation and trees. This mirrors the environment we can create for them in a home aquarium.
To recreate their natural habitat, we need to focus on providing a similar environment in our aquariums. This demands effort, but the vibrant colours and engaging behaviours of Ember Tetras make it a rewarding endeavour.
Behavior and Socialization
The Ember Tetra is a peaceful and social fish that thrives best in groups.
They are not aggressive and can live well with other small, peaceful fish species.
To reduce stress and promote natural behavior, it's essential to keep them in groups of at least 6 to 10 individuals.
Fire tetras are not shy and exhibit lively and active behavior, making them a joy to watch in a well-maintained aquarium.
They are active and usually swim in the middle waters of the aquarium, so be sure to provide plenty of space for them to roam.

Suitable Tank Mates

When choosing tank mates for your Ember Tetras, it's essential to select peaceful and small species that won't outcompete them during feeding.
Ember Tetras can be kept with other small, peaceful fish species, such as Neon Tetras and Cardinal Tetras.
Rasboras like Harlequin Rasbora and Espei Rasbora are also suitable roommates for Ember Tetras.
Small Catfish like Pygmy Corydoras and Otocinclus can thrive in the same tank as Ember Tetras.
In addition to fish, small invertebrates like shrimp and snails can also make good tankmates for Ember Tetras.
Here's a list of some suitable tank mates for Ember Tetras:
- Neon Tetra
- Cardinal Tetra
- Harlequin Rasbora
- Espei Rasbora
- Pygmy Corydoras
- Otocinclus
- Dwarf Gourami
- Shrimp
- Snails
Breeding and Reproduction
Breeding a group of Ember Tetras can be a fun and rewarding experience.
Ember Tetras can be bred in a regular aquarium, but a dedicated breeding aquarium is recommended for optimal results.
A smaller aquarium of about 20 liters is sufficient for breeding, with water parameters between pH 5.0 and 7.0 and a temperature of 26-28°C.

Dim lighting is essential to reduce stress and simulate a natural environment, and an air-driven sponge filter or air stone should be used to ensure adequate oxygen and water movement.
Conditioning the adult Ember Tetras with a diet of small live and frozen foods such as Artemia nauplii, Moina, and grindal worms can help encourage breeding.
A breeding group can consist of one or two males and several females, with a ratio of 1:2 or 1:3.
Breeding
Breeding Ember Tetras is a relatively straightforward process that occurs naturally without much intervention. To begin, prepare a separate tank with females and males, dim lighting, and maintain a pH of around seven, with the temperature a few degrees higher than their usual range.
The ideal breeding tank size is about 20 liters, which is sufficient for breeding Ember Tetras. A smaller tank size allows for easier monitoring and maintenance.
For optimal results, a dedicated breeding aquarium is recommended over a regular aquarium. This is because a breeding aquarium provides a controlled environment that mimics the natural conditions of the fish's wild habitat.

To condition the fish, feed them a diet of small live and frozen foods such as Artemia nauplii, Moina, and grindal worms for a few weeks before spawning. This will help encourage the breeding process.
After spawning, both parents will leave the fry to fend for themselves, so it's essential to move them to a fry tank where you can help them grow and prevent them from being eaten. The fry will be free-swimming after about three days and will start to search for their food.
To increase the chances of getting both males and females, it's recommended to buy at least six fish. This will give you a higher chance of sexing them correctly, as males are slender in profile, while females have rounder bodies, especially when viewed from above.
In a breeding group, the ratio of males to females can be 1:2 or 1:3. This allows the females to become full of eggs, and the males will help fertilize them.
To prevent the parents from eating the eggs, cover the bottom of the tank with a fine mesh net, a layer of glass marbles or coarse plastic grass. This will give the eggs a safe place to attach.
By following these simple steps and providing a suitable environment, you can successfully breed Ember Tetras and enjoy the thrill of watching them grow and thrive.
Sexual Dimorphism
Sexual Dimorphism can be a challenge when it comes to identifying the sex of Ember Tetras, especially for beginners.
Male Ember Tetras are known for their vibrant and vivid colouration, making them stand out from the females.
Females, on the other hand, tend to be slightly larger in size.
They also have a rounder body shape compared to the males, which can be a helpful distinguishing feature.
Determining the sex of Ember Tetras requires a keen eye for detail and some experience with these beautiful fish.
