About Ember Tetras

The ember tetra (Hyphessobrycon amandae) is a small freshwater fish popular among aquarium enthusiasts due to its vibrant color and peaceful nature. This species belongs to the Characidae family and is native to the Araguaia River basin in Central Brazil.

Physical Description

Ember tetras are known for their striking orange-red coloration, which intensifies in well-maintained aquariums. They are small, typically reaching only about 0.8 to 1 inch (2 to 2.5 cm) in length. Their bodies are slender and slightly elongated, with a characteristic high dorsal fin. The intensity of their color can serve as an indicator of their health and water conditions.

Habitat and Lifestyle

In the wild, ember tetras inhabit slow-moving, blackwater streams and rivers where the water is often acidic and stained dark by tannins from decaying plant matter. They are schooling fish and thrive in groups, displaying more vivid colors and engaging behaviors when in the company of their kind.

Aquarium Care

Ember tetras are favored in the aquarium hobby for several reasons, including their peaceful temperament and small size, making them ideal for community tanks and nano aquariums. Regarding ember tetra care, hey prefer soft, acidic water and a well-planted environment that mimics their natural habitat. These conditions not only provide them with hiding spots but also help in maintaining their vibrant coloration.

Water parameters should be stable, with a temperature range of 73-84°F (23-29°C), a pH between 5.5 and 7.0, and soft water. Regular water changes and good filtration are essential to keep them healthy.


In the wild, ember tetras primarily feed on small insects, larvae, and plant matter. In aquariums, they should be provided with a varied diet that includes high-quality flake food, as well as frozen or live foods like brine shrimp and daphnia. This varied diet helps maintain their color and overall health.

Community Tank Compatibility

Due to their peaceful nature, ember tetras make excellent inhabitants for community tanks. They do well with other small, peaceful fish species. However, they should not be kept with large or aggressive fish that may see them as prey.

Overall, the ember tetra is a beautiful and fascinating species suitable for both novice and experienced aquarists. Their care requires attention to water quality and diet, but their stunning appearance and peaceful demeanor make them a rewarding choice for any freshwater aquarium.

What Do Ember Tetra Eggs Look Like?

So, what do ember tetra eggs look like? Ember tetra eggs are small and delicate, reflecting characteristics typical of many small freshwater fish species. Here’s a detailed description of their eggs:

  • Size: The eggs of ember tetras are very small, typically about 1 millimeter in diameter. Due to this tiny size, they can be quite hard to spot in an aquarium, especially if it is densely planted or has a substrate that can camouflage the eggs.
  • Color: Initially, ember tetra eggs are mostly transparent, sometimes with a slight whitish or creamy tint. This transparency allows for the observation of the developing embryo inside the egg under the right conditions. As the eggs mature, they may become a bit more opaque but generally remain quite translucent.
  • Texture and Shape: These eggs are smooth and round, with a sticky surface. This stickiness helps them adhere to plants, substrate, or other surfaces in the aquarium where the female ember tetra has deposited them. In breeding setups, aquarists often use fine-leaved plants or spawning mops as a substrate for the eggs.
  • Visibility and Count: Spotting ember tetra eggs in an aquarium can be a challenge due to their size and transparency. A female ember tetra can lay dozens of eggs in a single spawning, although not all of them may be viable. The viable eggs keep their clear appearance, while non-viable ones or those affected by fungal infections usually turn white and opaque.
  • Development: In optimal conditions, the eggs hatch within about 24 to 36 hours after being laid. If observed closely, one might see the embryo developing within the egg, leading up to the emergence of the tiny fry.

Maintaining ideal water conditions is essential for the health and viability of the eggs. This includes stable water temperature, soft acidity, and cleanliness to prevent fungal infections, which are common problems with fish eggs in aquarium settings.

Spawning Behavior

The spawning behavior of ember tetras is an interesting aspect of their biology, exhibiting typical characteristics of many small, egg-scattering freshwater fish. Understanding their spawning behavior is crucial for successful breeding, especially in an aquarium setting. Here’s a detailed look into how ember tetras spawn:

Pre-Spawning Behavior

  • Conditioning for Spawning: Before spawning, ember tetras often require a period of conditioning. This involves providing them with high-quality food, such as live or frozen brine shrimp and daphnia, to stimulate spawning. The goal is to mimic the abundance of food they would encounter in their natural habitat during the breeding season.
  • Selecting a Mate: Ember tetras are not known for having elaborate courtship rituals. Males may display more vibrant colors and show slightly more active behavior to attract females. However, their mating process is generally straightforward and lacks the complexity seen in some other fish species.

Spawning Process

  • Environment: Ember tetras prefer soft, acidic water conditions for spawning, similar to their native habitats in the Araguaia River basin. Water temperature is also a crucial factor, with optimal spawning conditions usually between 75 and 82 degrees Fahrenheit (24-28 degrees Celsius).
  • Egg Scattering: Ember tetras are egg scatterers, meaning they do not exhibit parental care for their eggs or fry. During spawning, the female releases eggs into the water column, often among plants or other substrates, while the male fertilizes them. These eggs are adhesive and will stick to plants, the substrate, or any available surface.
  • Spawning Sites: In the wild, they tend to spawn in areas with dense vegetation. In aquariums, breeders often provide spawning mops or fine-leaved plants like Java moss to serve as a substrate for the eggs.

Post-Spawning Behavior

  • No Parental Care: After spawning, neither parent exhibits any parental care. In fact, if given the opportunity, they may consume the eggs. Therefore, it’s common practice in aquarium breeding to remove the adult fish from the breeding tank immediately after spawning.
  • Frequent Spawning: Ember tetras can spawn frequently, especially in well-maintained aquariums with optimal conditions. A single female can lay a few dozen eggs during each spawning event.

Challenges in Breeding

  • Egg Protection: Protecting the eggs from being eaten is one of the main challenges in breeding ember tetras. Using a separate breeding tank and removing the adults post-spawning are common strategies.
  • Water Quality: Maintaining high water quality is crucial for the development of the eggs. Poor water conditions can lead to fungal infections of the eggs or other developmental problems.

The spawning behavior of ember tetras, while not overly complex, requires specific conditions for success. Aquarists aiming to breed these fish need to provide an environment that closely mimics their natural habitat, ensure high water quality, and take measures to protect the eggs and fry for successful breeding outcomes.

Safety of Eggs and Fry

  • Protection from Predation: In a community tank, there is a high risk of eggs and fry being eaten by other fish, including the parent ember tetras. A breeding tank ensures that the eggs and newly hatched fry are safe from predation.
  • Isolation from Adult Fish: After spawning, adult ember tetras can potentially consume their eggs. A breeding tank allows breeders to remove the adults immediately after spawning, protecting the eggs.

Monitoring and Care

  • Close Observation: A breeding tank allows for close monitoring of the eggs and fry. This includes watching for signs of hatching, ensuring the fry are feeding properly, and observing any health issues that may arise.
  • Specialized Care: Fry require special care, including appropriate food sizes and frequent feeding. In a breeding tank, it’s easier to provide this level of care without impacting other fish or the overall balance of a community tank.

Encouraging Spawning Behavior

  1. Mimicking Natural Conditions: Ember tetras are more likely to spawn in conditions that mimic their natural habitat. A breeding tank can be set up with fine-leaved plants or spawning mops, soft acidic water, and subdued lighting to encourage spawning behavior.
  2. Stress Reduction: A less crowded and quieter environment can reduce stress for the breeding pair, increasing the likelihood of successful spawning.

Efficiency and Success Rates

  1. Higher Survival Rates: By controlling the environment and protecting the offspring, a breeding tank significantly increases the survival rate of the eggs and fry.
  2. Selective Breeding: For those interested in selective breeding, a breeding tank allows for the control of breeding pairs, ensuring specific traits or qualities are passed on.

A breeding tank is not just a luxury but a necessity for anyone serious about breeding ember tetras. It provides a controlled environment tailored to the needs of the fish during this critical phase, significantly increasing the chances of successful spawning and raising healthy fry.
