Description:
Endler Guppies are small, energetic livebearers known for their intense colouration and sleek body shape. Many display bright, fluorescent tones and striking patterns such as spots, bars, speckling, or metallic sheen. Their fins are typically short and streamlined, giving them a fast, active appearance. Males are the most colourful, while females are larger with a fuller body shape and more subdued colouring.
These fish are generally hardy and well suited to typical freshwater tropical aquariums. They thrive in planted tanks where they can graze, explore, and use vegetation as cover. Stable conditions and warm temperatures support their activity, colour, and breeding. Due to their small size, they are ideal for smaller aquariums, though they always benefit from extra swimming space and dense plant cover. Avoid housing them with large or aggressive species, as their size and bright colours can make them targets.
Temperament:
Endler Guppies are peaceful, social, and constantly active. They spend much of their time exploring the tank, interacting with one another, and displaying, especially the males. Chasing behaviour is usually related to hierarchy or breeding and is rarely harmful, though maintaining a higher female-to-male ratio can help reduce stress on females. They occupy all levels of the aquarium and are particularly active near the surface during feeding. When both sexes are present, they will breed readily and can produce fry frequently, which may quickly increase population over time.
Diet:
Endlers are omnivorous, readily accepting a wide range of commercially available foods. Due to their small mouths, flake foods are best crushed before feeding. High-quality options such as Xtreme Community Crave Flakes or Xtreme Nice Crumble make excellent staples, providing balanced nutrition in a size suitable for both adults and growing fish. A varied diet including vegetable matter and occasional live or frozen foods will further support optimal health and colouration.
Breeding Behaviour:
Endlers are very easy to breed. Males use their gonopodium to fertilise females, and females can store sperm for several months, allowing a single mating to result in multiple batches of fry.
Pregnant females develop a gravid spot near the anal fin, and their abdomen becomes noticeably rounder. Gestation typically lasts around 3–4 weeks, depending on temperature and conditioning. As they near birth, females may become more restless or seek out quieter areas of the aquarium.
Fry are born fully formed and free-swimming, and can immediately be fed fine foods such as powdered fry food, crushed flakes, or baby brine shrimp. Adult fish, including the parents, may consume newborn fry, so dense plant cover, such as java moss, guppy grass, hornwort, and floating plants, greatly improves survival rates. For higher survival, pregnant females can be moved to a separate breeding tank shortly before giving birth and returned afterwards.
Batch sizes vary depending on the female’s size and age, ranging from small drops to several dozen fry. With proper feeding and adequate cover, many fry will survive, so it’s important to have a plan in place for managing population growth, such as separating sexes, rehoming, or maintaining single-sex groups.

Acclimation Guide:
- 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.
- Feeding Behaviour: New fish may not eat any food for the first 12-24 hours whilst it is settling into its new environment, please allow some time before feeding as the food may go to waste.
