It is a small and strikingly beautiful fish that has gained immense popularity among aquarium enthusiasts in recent years. Originating from the rivers and streams of Venezuela, this vibrant species captivates with its dazzling colours, active nature, and ease of care.

In this comprehensive care guide, we will delve into the various aspects of providing optimal care for Endler Livebearers. From setting up the ideal aquarium environment to selecting suitable tank mates, understanding their breeding behaviour, and ensuring a well-balanced diet, we will cover everything you need to know to keep these captivating fish happy and healthy.

Overview

Physical Description

These tiny fish have an elongated body shape with a slender profile. Males typically grow up to 2 cm (0.8 inches) in length, while females are slightly larger, reaching around 3 cm (1.2 inches). The males showcase an array of radiant colours, including shades of blue, green, orange, red, and yellow. They also exhibit distinctive markings in the form of iridescent stripes or spots along their bodies. The females while a lot more muted are still beautiful.

Endler Livebearers have a large, upward-facing mouth and prominent eyes, which give them an alert and curious appearance. Their dorsal fin is typically larger in males, with a characteristic lyre-shaped or fan-like structure. Females, on the other hand, have a more rounded dorsal fin.

Aquarium Setup

Setting up the ideal aquarium environment is crucial for the health and well-being of your Endler Livebearers. Providing a suitable habitat will not only ensure their comfort but also promote their natural behaviours and vibrant colours. In this section, we will guide you through the key aspects of aquarium setup for Endler Livebearers, including tank size, water parameters, filtration, substrate, decorations, and the benefits of incorporating live plants.

Tank Size and Dimensions:

• Endler Livebearers are relatively small fish, so a tank size of at least 38 litres or 10 gallons is suitable for a small group. However, larger tanks offer more stability and allow for a more dynamic environment.
• Consider the dimensions of the tank to provide ample swimming space for the active nature of the fish. A longer and wider tank is preferable over a tall one, as it mimics their natural habitat and allows for horizontal swimming.

Water Parameters:

• Temperature: These fish are fairly hardy and can tolerate a wide range of temperatures. However, to keep their stress levels as low as possible and to prolong their lifespan, choose a stable value between 22°C and 28°C (72°F – 82°F). Use a reliable heater to make sure that there aren’t any major fluctuations.
• pH: Endler Livebearers prefer slightly alkaline water with a pH range of 7.0 to 8.5.
• Hardness: The water hardness should be moderately hard, around 10 to 25 dGH, to replicate their native habitats. Test the water hardness using a reliable test kit and make adjustments if necessary.
• Other parameters: Make sure that the tank is properly cycled and monitor ammonia and nitrite to make sure that they are always at 0 ppm. Test for nitrate levels as well and ensure that it stays below 25 ppm.

Filtration and Water Circulation:

• A good filtration system is essential to keep the water clean and free from harmful substances. Choose a filter that provides mechanical, chemical, and biological filtration to maintain water quality. The filter should be rated for 150% of the volume of water. For example, if you have a 38 litre tank, choose a filter with a filtration rate of at least 57 litres per hour.
• Opt for a gentle flow to mimic the calmer waters that Endler Livebearers prefer. Moderate water movement helps maintain oxygen levels and prevents stagnant areas in the tank.

Substrate and Decorations:

• Use a fine-grained substrate like sand or small-sized gravel to mimic their natural environment and enable them to forage for food.
• Decorate the tank with driftwood, rocks, and caves to create hiding spots and territories for the Endler Livebearers. Smooth surfaces are preferable to avoid fin damage.
• Provide some open swimming spaces to accommodate their active nature.

Live Plants and Their Benefits:

• Adding live plants into the aquarium provides numerous benefits for Endler Livebearers. Plants oxygenate the water, absorb nitrates, and provide natural filtration.
• Choose hardy aquatic plants such as Java Fern, Anubias, Amazon Sword, or Vallisneria. These plants can tolerate a wide range of water conditions and are suitable for beginners.
• Live plants also offer shelter for fry and encourage natural behaviours, enhancing the overall well-being of the Endler Livebearers.

By carefully setting up the aquarium with the right tank size, appropriate water parameters, efficient filtration, suitable substrate, and well-chosen decorations and live plants, you can create a thriving and great looking habitat for your Endler Livebearers.

  • Size compatibility is essential to prevent the Endler Livebearers from being intimidated or becoming prey to larger tankmates.
  • Temperament is a crucial factor. Choose peaceful fish that will not exhibit aggressive behaviour or compete for resources with the Endler Livebearers.
  • Consider the swimming levels preferred by each species. Combining fish that occupy different water layers can help maximise the use of space within the aquarium.
    
    
• Suitable Species for a Harmonious Community Tank:
  • Guppies (Poecilia reticulata): Guppies are closely related to Endler Livebearers and make great tankmates. They come in a variety of colours and patterns, enhancing the visuals of the tank.
  • Tetras (Neon tetras, Cardinal tetras, Ember tetras): These small and peaceful fish are great companions for Endler Livebearers. They add movement and colour to the tank.
  • Rasboras (Harlequin Rasboras, Chili Rasboras): These peaceful fish are known for their vibrant colours and schooling behaviour, making them an excellent addition to the community tank.
  • Corydoras Catfish: These bottom-dwelling fish are peaceful and help keep the tank clean by scavenging for food particles.

By selecting peaceful and compatible tankmates, you can create a captivating and harmonious community tank that will leave anyone mesmerised.

Water Quality and Maintenance

Maintaining optimal water quality plays a huge role in the health and overall well-being of Endler Livebearers. Clean and well-maintained water promotes their vibrant colours, supports their immune system, and helps prevent the onset of diseases.

• Regular Water Testing and Maintenance Routines:
  
  
  • Regularly test the water parameters in your Endler Livebearer aquarium using reliable test kits. Monitor pH, ammonia, nitrite, nitrate, and other relevant parameters to ensure they are within acceptable ranges.
  • Establish a routine for water testing, such as weekly or bi-weekly (I do mine weekly), to identify any potential issues early on and take appropriate action.
    
    
• Water Changes and Proper Filtration for a Healthy Environment:
  
  
  • Perform regular partial water changes to maintain optimal water quality. Aim for 20-50% water changes every one to two weeks, or as needed based on test results.
  • Use a gravel vacuum during water changes to remove uneaten food, waste, and other debris that may accumulate in the substrate.
  • Adequate filtration is crucial for a healthy Endler Livebearer tank. Choose a filter that provides mechanical, chemical, and biological filtration. Ensure that the filter is properly sized for the tank and follow the manufacturer’s recommendations for maintenance.
    
    
• Managing Ammonia, Nitrite, and Nitrate Levels:
  
  
  • Ammonia and nitrite are highly toxic to fish and can cause serious health issues. Monitor these levels closely, especially during the initial cycling period of a new tank, and ensure they remain at or near zero.
  • Nitrate is a byproduct of the nitrogen cycle and should be kept at acceptable levels (below 25 ppm). Regular water changes help reduce nitrate levels and maintain water quality.
    
    
• Dealing with Common Water Quality Issues:
  
  
  • Cloudy water: Cloudiness can be caused by particles in the water or an imbalance in the aquarium. Perform regular water changes, clean the filter media as needed, and ensure proper filtration to resolve this issue.
  • Algae growth: Algae can be controlled by maintaining proper lighting duration, avoiding excessive nutrient levels (phosphates and nitrates), and ensuring adequate water flow and oxygenation. Additionally, regular cleaning of the aquarium and controlling nutrient inputs can help prevent algae outbreaks.
  • pH fluctuations: Fluctuations in pH can be stressful for Endler Livebearers. Ensure a stable pH by performing regular water changes, using buffering agents if necessary, and avoiding sudden changes in water parameters.

By implementing regular water testing and maintenance routines, performing proper water changes, employing effective filtration, managing ammonia, nitrite, and nitrate levels, and addressing common water quality issues promptly, you can create a clean and healthy environment for your Endler Livebearers to thrive and display their vibrant colours.

Breeding

Breeding Endler Livebearers can be a rewarding and fascinating experience for aquarium enthusiasts. These colourful and active fish are known for their prolific breeding habits. By understanding their reproductive behaviour and providing optimal conditions, you can encourage successful breeding and care for the resulting fry.

• Understanding the Reproductive Behaviour of Endler Livebearers:
  
  
  • Endler Livebearers , as the name makes it clear, are livebearers, meaning they give birth to live fry rather than laying eggs. The male fish have a modified anal fin called a gonopodium, which they use to transfer sperm to the female during mating.
  • The females store sperm internally and can produce multiple broods from a single mating.
  • The gestation period for Endler Livebearers is typically around 28-35 days, but this can vary.

  • Include dense vegetation, such as floating plants, to provide hiding spots for fry and protect them from potential predation by adult fish.
    
    
• Breeding Techniques and Tips for Successful Reproduction:
  
  
  • Introduce a ratio of one or two males to every three or four females to prevent excessive harassment of individual females (the males are relentless and can often harass females to death, I kid you not!).
  • Incorporate breeding traps or use floating spawning mops to separate pregnant females and protect the fry.
  • Provide a varied diet rich in high-quality foods, including live or frozen foods, to ensure the health and reproductive success of the fish.
    
    
• Caring for Fry and Promoting Their Growth:
  
  
  • Once the female gives birth, remove her from the breeding tank to prevent her from consuming the fry.
  • Feed the fry with appropriate-sized foods, such as baby brine shrimp, crushed flakes, or powdered fry food. Offer frequent small meals to ensure they receive adequate nutrition.
  • Maintain good water quality and perform regular water changes to prevent the accumulation of waste and maintain optimal conditions for the fry’s growth.

Remember to observe and monitor the breeding tank closely, as well as provide appropriate care and nutrition for the fry. Breeding Endler Livebearers can result in a flourishing population of these beautiful fish in your aquarium. With patience, proper conditions, and adequate care, you can enjoy the process of breeding and witnessing the growth and development of the Endler Livebearer fry.
