Description:
Endler Guppies (Poecilia wingei) are renowned for their vibrant colours and intricate patterns. Males typically display vivid hues such as red, blue, green, orange, and yellow, often arranged in striking patterns like stripes, spots, or speckles. Their iridescent sheen adds to their visual appeal as they swim gracefully through the water. Females, in contrast, are generally larger and exhibit more subdued, monochromatic tones.
In terms of body shape, Endler Guppies possess a slender and streamlined physique, especially noticeable around the rear portion of the body, they are generally much smaller than your common Guppy (Poecilia reticulata). Additionally, Endlers typically have smaller, more restrained fins compared to the often larger fins of fancy guppies.
When Endler Guppies crossbreed with regular guppies, the resulting hybrids often exhibit a blend of characteristics from both parent species. These hybrids tend to have an intermediate body shape, more streamlined than pure guppies but slightly more robust than pure Endlers. They often inherit the brilliant, fluorescent colours of the Endler, combined with the larger size and fin variations of the guppy. This fusion results in a unique and visually captivating fish that showcases the best traits of both species.
Endlers are remarkably robust and undemanding in aquarium setups, thriving well under typical freshwater tropical conditions. They particularly excel in planted tanks, mirroring their natural habitat. While they prefer warmer, harder water around 26-27°C, they adapt to varying conditions, although warmer temperatures can accelerate their growth but might shorten their lifespan. Their small size makes them perfect for smaller aquariums, yet they appreciate spacious environments if available. Due to their small size, it's best to avoid housing Endler guppies with larger predatory fish. They thrive best when kept among similarly sized or smaller fish, as well as other peaceful community fish.
Temperament:
Known for their peaceful demeanour, Endler Guppys coexist harmoniously with other gentle fish in community setups. They are incessantly active, exploring their surroundings, foraging algae, and engaging in displays or interactions. While they establish hierarchies, conflicts are rare, limited to playful chasing or relentless breeding. They roam all parts of the aquarium, sometimes congregating at the bottom or near the surface, especially in tanks with larger bottom dwelling fish. Breeding occurs readily without special preparations, as long as both genders are present. Endlers give birth to live fry approximately every 23-30 days, with females capable of storing sperm for later fertilisation, leading to continuous reproduction even without males present.
Diet:
Endler Guppys are omnivorous, accepting various commercially available foods. However, flake foods should be crushed for their small mouths. A balanced diet including vegetables and occasional live or frozen foods ensures optimal health. They readily recognise feeding schedules and get extremely excited when you go near the aquarium. While adult Endlers can prey on their young, fry are most vulnerable to other tank mates. Providing hiding spots or a densely planted environment increases their survival chances. Alternatively, raising fry separately until they grow too large to be eaten by the parents or other tank mates is advisable. Endler guppy fry will grow rapidly with frequent feeding.
Breeding Behaviour:
Livebearers, such as guppies are some of the easiest fish to breed in the aquarium hobby. Unlike egg-laying species, livebearers give birth to fully-formed, free-swimming fry, making the process simple but also potentially overwhelming due to how quickly populations can grow.
Males constantly court females by displaying their colourful fins and using their gonopodium (a modified anal fin) to transfer sperm. Females can store sperm internally for several months, meaning a single successful mating can result in multiple batches of fry without needing a male present for every pregnancy.
Once pregnant, the female will begin to develop a gravid spot, a dark area near her anal fin and her belly will grow much rounder. Gestation usually lasts around 4 weeks, depending on species and temperature. Just before giving birth, the female may isolate herself in a quiet area of the tank or behave restlessly.
When she gives birth, the fry are immediately free-swimming and capable of feeding on tiny foods such as powdered fry food, crushed flakes, or baby brine shrimp. However, adult fish (including the parents) will often eat the newborn fry if given the chance. To improve survival rates, provide dense plants like java moss, hornwort, guppy grass, or any fast growing floating plant for hiding, or move the pregnant female to a separate breeding tank shortly before she gives birth.
Females can give birth to anywhere from a handful of fry to 50 or more in a single batch, depending on their size, age, and health, in some occasions these numbers can reach 100. After giving birth, she can be returned to the main tank, while the fry remain in their own tank or nursery area until they are large enough to avoid being eaten.

- Float the Bag: Place the unopened bag in your tank and let it float for 15–20 minutes. This lets the water inside the bag slowly match your tank’s temperature.
- Turn Off the Lights: Keep the aquarium lights off during this process. It helps keep things calm and prevents sudden temperature changes.
- Add a Bit of Tank Water: After floating, carefully open the bag and pour out about half the water into a sink or bucket (not into your tank). Then, slowly add small amounts of your tank water into the bag over 15–20 minutes. This helps your fish adjust to the new water conditions.
- Gently Move the Fish: Use a fish net to gently move your fish from the bag into the tank. Try not to pour the bag water into your tank — this helps keep your aquarium clean and healthy.
- Watch and Wait: It’s normal for fish to hide or act a bit shy at first. Keep an eye on them, and avoid doing a water change for the first 24 hours to give them time to settle in.
