What Are Endler Fish?

Endler fish (Poecilia wingei), also called Endler’s livebearers, are small freshwater fish native to Venezuela. They are closely related to guppies but are distinguished by their brighter hues and distinct patterns. Their compact size (usually 1.5 to 2 inches) makes them perfect for smaller tanks, and their active nature adds a splash of color to any aquatic setup.

Setting Up the Perfect Aquarium for Endler Fish

Tank Size and Environment

• Minimum Tank Size: 10 gallons is ideal for a small school of Endler fish.
• Water Temperature: Keep between 75°F and 82°F (24°C – 28°C). Use a reliable heater if necessary.
• pH Level: Maintain a pH of 7.0 to 8.0 for optimal health.
• Water Hardness: Endler fish prefer slightly hard water, around 10-20 dGH.
• Filtration: Use a gentle filter to keep water clean without creating strong currents.
• Substrate & Decorations: Use fine gravel or sand, and add plants, rocks, or hiding spots. Live plants like java moss and water lettuce help mimic their natural habitat.

Lighting

Provide moderate lighting to support plant growth and showcase their vibrant colors. A 10-12 hour light cycle is perfect.

Water Quality & Maintenance

• Weekly Water Changes: Replace 20-25% of the water weekly to prevent nitrate buildup.
• Water Testing: Regularly test for ammonia, nitrite, nitrate, and pH levels.
• Conditioning Water: Always use a water conditioner to remove chlorine or chloramine before adding water to the tank.

Feeding Your Endler Fish

Endler fish are omnivorous and thrive on a diverse diet:

• High-quality Flake Food: Specially formulated for small tropical fish.
• Frozen or Live Foods: Bloodworms, brine shrimp, daphnia—great for stimulating their natural appetite.
• Vegetables: Finely chopped spirulina or blanched vegetables can supplement their diet.

Feed them small amounts 2-3 times daily, avoiding overfeeding to maintain water quality.

Behavior & Compatibility

• Social Fish: Keep in groups of at least 6 to minimize stress and encourage natural behaviors.
• Tank Mates: Peaceful small fish like tetras, dwarf Corydoras, or other livebearers pair well with Endler fish.
• Avoid Aggressive Species: Larger or aggressive fish may harass or injure Endler fish.

Breeding Endler Fish

One of their most appealing traits is their prolific breeding. To promote healthy reproduction:

• Provide plenty of plants and hiding spots.
• Maintain stable water parameters.
• Separate males and females if you wish to control breeding, or allow them to breed freely in a community tank.
• Expect the female to give birth approximately every 30 days, with 20-50 tiny fry per batch.

Common Health Issues & Troubleshooting

• Ich (Ichthyophthirius): Look for white spots; treat with specific ich medication and increase tank temperature gradually.
• Fin Rot: Caused by poor water quality or injury; improve water conditions and consider antibacterial treatments.
• Stress Signs: Lethargy, hiding, or faded colors—address by ensuring optimal water quality, proper tank mates, and stable environment.
