Ember Tetras: Care, Habitat, and FAQs

Ember Tetras (Hyphessobrycon amandae) are one of the most popular choices for aquarium enthusiasts due to their vibrant colors and peaceful nature. These small, fiery fish are native to the Araguaia River basin in Brazil and have become a favorite for both beginners and experienced aquarists. In this comprehensive guide, we will explore everything you need to know about Ember Tetras, including their care requirements, habitat preferences, and answers to some frequently asked questions.

1. Introduction to Ember Tetras

Ember Tetras are small, schooling fish that bring a splash of bright orange color to any aquarium. Their peaceful temperament and ease of care make them an excellent choice for community tanks. These fish typically grow to about 0.8 inches (2 cm) in length, making them perfect for nano aquariums as well.

2. Natural Habitat and Distribution

Ember Tetras are found in the slow-moving waters of the Araguaia River basin in central Brazil. Their natural habitat includes densely vegetated areas with plenty of hiding spots. The water in these regions is typically warm, slightly acidic, and has a slow current.

3. Physical Characteristics

Ember Tetras are named for their striking orange-red coloration, which can vary in intensity depending on their environment and diet. They have a slender, streamlined body and a forked tail. Despite their small size, their vibrant colors make them stand out in any aquarium.

4. Tank Setup and Requirements

To provide the best environment for Ember Tetras, it’s essential to replicate their natural habitat as closely as possible.

Tank Size

While Ember Tetras are small, they thrive in groups. A 10-gallon tank is the minimum size recommended for a small school of 6-8 Ember Tetras. However, a larger tank is always better, especially if you plan to keep them with other fish.

Substrate

A dark substrate, such as fine gravel or sand, is ideal as it enhances their vibrant coloration. Additionally, it closely mimics their natural riverbed habitat.

Plants and Decorations

Ember Tetras feel most comfortable in a densely planted tank with plenty of hiding spots. Live plants like Java Moss, Anubias, and Amazon Swords are excellent choices. Floating plants can also help diffuse the light and create a more natural environment.

Lighting

Moderate lighting is sufficient for Ember Tetras. Too much light can stress them, so it’s best to create shaded areas with plants or decorations.

5. Water Parameters

Maintaining the right water parameters is crucial for the health and well-being of Ember Tetras.

• Temperature: 73-84°F (23-29°C)
• pH: 5.5-7.0
• Hardness: 5-17 dGH
• Ammonia and Nitrites: 0 ppm
• Nitrates: < 20 ppm

Regular water changes (25-30% weekly) are essential to keep the water clean and free from harmful toxins.

6. Diet and Feeding

Ember Tetras are omnivores and have a relatively simple diet. In the wild, they feed on small insects, larvae, and plant matter. In an aquarium setting, they can be fed:

• High-quality flake food
• Micro pellets
• Freeze-dried or frozen foods like daphnia, brine shrimp, and bloodworms

It’s important to feed them small amounts several times a day rather than a large amount once a day. This feeding schedule mimics their natural feeding behavior and helps maintain water quality.

7. Behavior and Tank Mates

Ember Tetras are peaceful and social fish that thrive in groups of at least six. They are active swimmers and prefer to stay in the middle to upper levels of the tank. Due to their small size and gentle nature, they are compatible with a variety of other peaceful fish.

Suitable Tank Mates

• Other Tetras (e.g., Neon Tetras, Cardinal Tetras)
• Small Rasboras
• Corydoras Catfish
• Dwarf Gouramis
• Shrimp (e.g., Cherry Shrimp, Amano Shrimp)

Avoid keeping them with larger, aggressive fish that might see them as food.

8. Breeding Ember Tetras

Breeding Ember Tetras can be a rewarding experience, although it requires specific conditions to be successful.

Breeding Setup

• Tank: A separate breeding tank of about 5-10 gallons is recommended.
• Substrate: A bare bottom tank or one with a layer of marbles or mesh to protect the eggs from being eaten.
• Plants: Fine-leaved plants or spawning mops provide good surfaces for egg-laying.

Water Parameters for Breeding

• Temperature: 78-82°F (25-28°C)
• pH: 5.5-6.5
• Hardness: 1-5 dGH

Breeding Process

1. Condition the breeding pair with high-quality live or frozen foods.
2. Introduce the pair into the breeding tank.
3. The female will scatter eggs among the plants or substrate.
4. Remove the adults after spawning to prevent them from eating the eggs.
5. The eggs will hatch in about 24-36 hours, and the fry will become free-swimming in 3-4 days.

9. Common Health Issues

Ember Tetras are generally hardy, but like all fish, they can be susceptible to certain diseases.

Common Health Issues

• Ich: Characterized by white spots on the body and fins. Treat with a suitable ich medication and raise the tank temperature slightly.
• Fin Rot: Caused by bacterial infection, often due to poor water quality. Improve water conditions and treat with antibacterial medication.
• Fungal Infections: Appear as white, cotton-like growths on the body. Treat with antifungal medication.

Maintaining good water quality and a balanced diet can help prevent most health issues.
