The Blue Star Endler’s Livebearers Care Breeding, Tank Setup and Where To Buy

Here’s a care guide for Blue Star Endler Guppies, covering tank setup, feeding, disease prevention, and breeding:

Tank Setup:

  1. Tank Size: A 10 to 20-gallon aquarium is suitable for a small group of Blue Star Endler Guppies. Larger tanks provide more stable water conditions and allow for a larger population.
  2. Filtration: Use a good-quality aquarium filter to maintain water quality. Guppies are sensitive to ammonia and nitrite, so regular water changes are essential.
  3. Heating: Maintain a stable water temperature between 74°F to 82°F (23°C to 28°C) as Endler’s Guppies are tropical fish.
  4. Decor: Provide plenty of plants (live or artificial) and hiding spots, as these fish like to explore and take shelter. Floating plants are appreciated because they provide cover and help diffuse light.
  5. Substrate: Use a fine-grained substrate, like sand or fine gravel, as it’s easier on their delicate barbels.

Water parameters

  • pH: Maintain a slightly alkaline pH level between 7.0 and 8.0 to ensure the well-being of your Endler’s Livebearers.
  • Water Hardness: Aim for a general hardness (GH) level between 10 and 20 degrees, dGH. This range provides the necessary minerals for your fish.
  • Temperature: Keep the water temperature stable between 75-82°F (24-28°C) to mimic their tropical habitat.
  • Ammonia and Nitrites: Regularly test for ammonia and nitrite levels, aiming for undetectable levels. High levels can harm your fish.
  • Nitrates: Keep nitrate levels below 40 ppm (parts per million) through regular water changes and proper filtration.
  • Chlorine and Chloramine: Use a water conditioner to neutralize these chemicals in tap water, ensuring it’s safe for your fish.
  • Water Movement: Maintain gentle water movement, as Endler’s Livebearers prefer calm to moderately flowing water.
  • Water Quality: Regularly monitor water parameters and perform routine maintenance, including water changes, to keep your aquarium water clean and suitable for your fish.


  1. Diet: Blue Star Endler Guppies are omnivorous. Feed them a balanced diet that includes high-quality flake or pellet food. Supplement their diet with live or frozen foods like brine shrimp, daphnia, and bloodworms. Occasional offerings of blanched vegetables, like zucchini or spinach, can also be beneficial.
  2. Feed Regularly: Offer food in small portions 2-3 times a day. Ensure they consume their food within a few minutes to prevent overfeeding and water quality issues.

Disease Prevention and Troubleshooting:

  1. Quarantine: Always quarantine new fish before introducing them to your main tank to prevent the spread of diseases.
  2. Water Quality: Maintain good water quality through regular water changes, proper filtration, and monitoring parameters like pH, ammonia, nitrite, and nitrate.
  3. Stress Reduction: Minimize stress by avoiding sudden water parameter changes, overcrowding, and aggressive tankmates.
  4. Disease Identification: Familiarize yourself with common fish diseases and their symptoms. Isolate and treat sick fish promptly to prevent disease spread.


  1. Gender Separation: Male Blue Star Endler Guppies are smaller and have a modified anal fin called a gonopodium. Females have a rounder, fan-shaped anal fin.
  2. Breeding Tank: Consider setting up a separate breeding tank or providing plenty of hiding spots and dense vegetation in the main tank for fry to seek refuge.
  3. Mating Behavior: Males display their striking colors and perform courtship dances to attract females. Once the female accepts, the male transfers sperm using his gonopodium.
  4. Gestation: Female guppies are livebearers, and they give birth to live fry after a gestation period of about 21 to 30 days.
  5. Fry Care: When the female gives birth, move her to a separate tank or provide plenty of hiding spots to protect the fry from being eaten by adults. Feed the fry with powdered or liquid fry food or crushed flakes until they are large enough to eat regular food.
  6. Growth: Blue Star Endler Guppies grow quickly, and within a few months, they will reach maturity and start breeding themselves.
