As for their history in the aquarium hobby, Ember Tetras have been gaining popularity since the early 2000s, when they were first introduced to the scene. Their fiery appearance, combined with their peaceful nature, made them an instant hit among aquarists. Today, Ember Tetras are bred in captivity and readily available in most local fish stores and online.


Ember Tetras are known for their distinct and captivating appearance. Measuring between 0.8 to 1.2 inches (2-3 cm) when fully grown, they may be small, but they certainly make a statement.

Their bodies are near-translucent and adorned with a bright orange-red color, which gives them their characteristic ember-like glow. This fiery coloration is what sets them apart from other tetra fish species and makes them a popular choice for aquarists looking to add a touch of vibrancy to their tanks.

The brilliance of their colors can vary depending on factors such as age, diet, and stress levels. Ensuring optimal care, a balanced diet, and the right water parameters will help your Ember Tetras maintain their stunning appearance and stay healthy.

Ember Tetra Care

Providing the best care for your Ember Tetras is crucial for their health, happiness, and longevity. By understanding their specific needs and preferences, you can create an environment that helps them thrive and display their vibrant colors.

In this section, we will discuss the essentials of Ember Tetra care, including tank setup, water parameters, diet, and disease prevention. By following these guidelines, you’ll learn how to create the perfect home for your Ember Tetras and ensure they live their best lives in your aquarium.

Tank Setup

Tank Size

A minimum tank size of 10 gallons is recommended for a small group of 6-8 Ember Tetras. As a general rule of thumb, for every additional 1-2 Ember Tetras, you should increase the tank size by 2-3 gallons to accommodate their bioload and swimming space requirements. If you plan to house them with other fish species, be sure to factor in the size and needs of those species as well.

For instance, if you’re adding a group of Corydoras catfish, which require an additional 2-3 gallons per fish, you would need to adjust the tank size accordingly.

In most cases, a 20-gallon long tank or larger is preferable for a community setup with multiple species.

What to Put In Their Tank

Ember Tetras enjoy a planted aquarium that mimics their natural habitat. Incorporate a variety of live plants, such as Java Fern, Anubias, and Vallisneria, to provide shelter and hiding spots.

Adding driftwood and leaf litter can also help create a more authentic environment. Floating plants can be used to diffuse lighting and make the tetras feel more secure.


A good-quality filter is essential for maintaining water quality and ensuring the health of your Ember Tetras. Choose a filter with a gentle flow rate, as these fish prefer slow-moving waters. A sponge filter or hang-on-back filter with adjustable flow can work well for this purpose.


Ember Tetras prefer a dark-colored, soft substrate, which helps them feel more at ease and can also enhance their vibrant colors. Fine sand or smooth gravel can be used as the substrate for their tank. Make sure to clean the substrate regularly to prevent the buildup of debris and maintain water quality.

Water Parameters

Maintaining the appropriate water parameters is essential for the health and well-being of your Ember Tetras. Since they originate from blackwater habitats in the wild, they prefer soft, slightly acidic water. Here are the ideal water parameters for Ember Tetras:

  • Temperature: 73-84°F (23-29°C). Aim for a stable temperature within this range, as fluctuations can cause stress and lead to health issues.
  • pH: 5.5-7.0. Ember Tetras do best in slightly acidic water. Regularly test and monitor the pH levels to ensure they remain within this range.
  • Hardness: 1-10 dGH (soft to moderately hard water). These fish thrive in soft water conditions, so it’s essential to maintain the appropriate water hardness.
  • Ammonia, Nitrite, and Nitrate: Ammonia and nitrite levels should always be at 0 ppm, as any presence can be harmful to your fish. Keep nitrate levels below 20 ppm, as high concentrations can be detrimental to their health.

To maintain optimal water parameters, perform regular water tests using a reliable aquarium test kit. Conduct 25-30% water changes weekly to keep the water clean and stable. If needed, use water conditioners, buffering agents, or RO water to adjust the water parameters to match the needs of your Ember Tetras.

Diet and Feeding

A balanced diet is essential for the health and coloration of your Ember Tetras. These fish are omnivorous and require a mix of both plant-based and protein-rich foods to thrive. Here are some guidelines to ensure your Ember Tetras receive the nutrition they need:

  • Staple diet: High-quality, small-sized tropical fish flakes or micro pellets make up the staple diet for Ember Tetras. These foods are formulated to provide essential nutrients and should be fed to your fish daily.
  • Live and frozen foods: Supplement the staple diet with live or frozen foods, such as brine shrimp, daphnia, and bloodworms, to provide variety and additional protein. Feeding live or frozen foods 2-3 times per week will help enhance your fish’s coloration and overall health.
  • Vegetable matter: Although not a major part of their diet, incorporating some vegetable matter, such as blanched spinach or spirulina flakes, can help ensure they receive a well-rounded diet.

An important note on feeding frequency: Feed your Ember Tetras small portions 2-3 times per day, providing only as much food as they can consume within 2-3 minutes. Overfeeding can lead to water quality issues and obesity, so it’s crucial to monitor their food intake and adjust as needed.

Remember that the dietary needs of your fish may change with age, water conditions, and activity levels. Regularly observe your Ember Tetras to ensure they remain healthy and well-fed.

Common Diseases

Like all fish, Ember Tetras can be susceptible to various diseases if not properly cared for. Maintaining optimal water conditions, providing a balanced diet, and reducing stress are crucial for preventing health issues. Here are some common diseases to watch out for and tips on how to address them:

Ich (White Spot Disease)

Ich is a common parasitic disease that causes white spots on the fish’s body, gills, and fins. Affected fish may also exhibit signs of distress, such as rubbing against objects or rapid breathing.

To treat Ich, increase the water temperature to 86°F (30°C) for a few days and use over-the-counter Ich medication as directed.

Fin Rot

Fin rot is a bacterial or fungal infection that causes the fish’s fins to appear ragged or disintegrate. Poor water quality is often the main cause.

Improve water conditions, perform regular water changes, and use antibacterial or antifungal medication to treat the infection.

Swim Bladder Disease

Swim bladder disease causes difficulty in maintaining buoyancy and swimming. Affected fish may swim at odd angles or have difficulty staying upright. This condition can result from overfeeding, constipation, or injury.

To address swim bladder disease, fast your fish for 2-3 days and then feed them a blanched, deshelled pea to help with digestion. If the issue persists, consult an aquatic veterinarian.

Internal Parasites

Internal parasites like nematodes and flukes are organisms that live inside the fish’s body, typically in the digestive tract, and can cause various health issues like weight loss, bloating, and lethargy.

To treat internal parasites, use an anti-parasitic medication designed for aqufish and follow the instructions provided.

Regularly monitor your Ember Tetras for any signs of illness and act quickly to address any health concerns. Quarantine any new fish or plants for at least two weeks before introducing them to your main tank to prevent the introduction of diseases or parasites.

Breeding Ember Tetras

Gender Differences

To begin, it’s important to know how to distinguish between male and female Ember Tetras. Males and females share similar coloration, but males tend to have slightly more intense hues.

Also, males are often a bit slimmer and more streamlined compared to their female counterparts. As they swim around the tank, their vivid colors shimmer and create an enchanting display, especially when they’re kept in a group.

Breeding Tips

We’ve put together these instructions for you to follow to increase your chances of breeding success:

  1. Set up a separate breeding tank: Prepare a dedicated breeding tank with a 5-10 gallon capacity. Add a soft, dark substrate, some fine-leaved plants or spawning mops, and a sponge filter. Keep the water parameters within the optimal range for Ember Tetras, and maintain a slightly warmer temperature of around 80°F (27°C) to encourage spawning.
  2. Condition the breeding pair: Select a healthy, mature pair of Ember Tetras and condition them with a high-quality diet of live or frozen foods. This will help improve their overall health and encourage them to breed.
  3. Introduce the breeding pair: Place the conditioned male and female Ember Tetras into the breeding tank, ensuring that they have plenty of hiding spots and feel secure. Dimming the lights or using floating plants can help create a more comfortable environment for them.
  4. Monitor for spawning: If conditions are favorable, the breeding pair will likely spawn within a few days. The female will lay her eggs among the plants or spawning mops, and the male will follow to fertilize them. Ember Tetra eggs are tiny and transparent, making them difficult to see.
  5. Remove the adults: After spawning, it’s crucial to remove the adult Ember Tetras from the breeding tank, as they may eat the eggs or fry. Monitor the eggs closely, as they should hatch within 24-48 hours.
  6. Raising the fry: Once the eggs have hatched, you’ll need to provide the fry with suitable food. Start by feeding them infusoria or liquid fry food for the first few days. As they grow, gradually introduce larger food options like baby brine shrimp and microworms.
  7. Gradual transition: As the fry grow and become more independent, monitor their development and adjust the water parameters to match those of the main tank. Once the fry are large enough, you can safely transfer them back to the main aquarium or a grow-out tank.

Remember that patience is key when breeding Ember Tetras. It may take several attempts to achieve successful spawning, but with persistence and attention to detail, you can enjoy the fascinating process of raising these beautiful fish.
