Origins of the Yellow Tiger Endler Guppy
The Yellow Tiger Endler Guppy is a selectively bred variety of Endler’s livebearer (Poecilia wingei), a species discovered in Venezuela around Lake Valencia in the 1970s. Endlers were originally collected by Dr. John Endler, hence their name. These fish lived in shallow, warm, plant-rich lagoons and streams, where their small size and vivid colors helped them thrive.
Selective breeding by aquarists led to the development of stunning color variations such as the Yellow Tiger. This particular strain displays brilliant yellow tones enhanced with dark stripes resembling tiger markings, making it stand out among other Endler and guppy varieties. Some Yellow Tiger Endlers are pure Endler’s livebearers, while others may be hybrids with common guppies (Poecilia reticulata), which can influence size and pattern.
Appearance and Coloration
The defining feature of the Yellow Tiger Endler Guppy is its vivid coloration. Males exhibit bright yellow shades across their body and fins, combined with vertical or horizontal black stripes that give a tiger-like pattern. Some may show orange highlights near the fins or tail, while others display metallic green or blue reflections under proper lighting.
Males typically grow to 1 inch (2.5 cm), making them smaller than most guppies. Females are larger at around 1.5–2 inches (4–5 cm), but they are less colorful, often appearing pale yellow or silver with faint markings. The contrast between the dazzling males and more muted females makes breeding groups visually interesting in aquariums.
Behavior and Temperament
Yellow Tiger Endler Guppies are peaceful, energetic, and social. They are schooling fish that prefer to be kept in groups of 6 or more. Their constant movement and playful swimming add life to aquariums.
They are not aggressive, but males can be persistent when chasing females for breeding. To reduce stress, it is recommended to keep a ratio of 1 male to 2–3 females. Yellow Tiger Endlers do well in community tanks with other small, non-aggressive fish species.
Unlike some territorial fish, Endlers rarely nip fins or harass tank mates. Instead, they spend their time exploring plants and searching for food in all areas of the tank, from the surface to the bottom.
Tank Requirements for Yellow Tiger Endler Guppy
While Yellow Tiger Endler Guppies are hardy and easy to care for, providing optimal conditions ensures they display their best colors and live longer, healthier lives.
Tank Size
A group of 6–8 Yellow Tiger Endlers can be comfortably housed in a 10-gallon tank, though larger aquariums are ideal. In community tanks, 20 gallons or more provides plenty of space for multiple species.
Water Parameters
- Temperature: 72–82°F (22–28°C)
- pH: 6.5–8.0
- Hardness: 10–20 dGH
- Ammonia/Nitrite: 0 ppm
- Nitrate: below 20 ppm
Endlers are highly adaptable but thrive best in stable, clean water. Sudden fluctuations in temperature or pH can stress them, so a heater and regular water changes are recommended.
Filtration and Aeration
A gentle sponge filter or small hang-on-back filter works well. Since Yellow Tiger Endlers are small and prefer calm waters, avoid strong currents. Proper filtration helps maintain water clarity and quality, while aeration ensures oxygen levels are sufficient.
Substrate and Decor
Dark substrates enhance their bright yellow coloration. Live plants such as guppy grass, Java moss, hornwort, and anacharis create hiding spaces and breeding grounds. Adding driftwood, smooth stones, and caves provides natural shelter and improves tank aesthetics.
Lighting
Moderate lighting is ideal. Strong light promotes plant growth, which benefits Endlers by providing cover and food sources, while also enhancing their colors.
Diet and Feeding
Yellow Tiger Endler Guppies are omnivores with a varied diet in the wild, including algae, small insects, and plant matter. In aquariums, they should be provided with a balanced mix of commercial and natural foods.
Recommended Foods
- Flakes & Pellets: High-quality tropical micro-pellets and flake food as a staple
- Frozen & Live Foods: Brine shrimp, daphnia, mosquito larvae, bloodworms, and microworms for protein
- Vegetable-Based Foods: Spirulina flakes, blanched zucchini, cucumber, or spinach for fiber and plant nutrition
Feed small amounts 2–3 times per day, ensuring all food is consumed within a few minutes. Overfeeding can lead to poor water quality and health issues.
Breeding Yellow Tiger Endler Guppy
Like other Endler and guppy varieties, Yellow Tiger Endlers are prolific breeders. They are livebearers, meaning females give birth to free-swimming fry rather than laying eggs.
Breeding Facts
- Gestation Period: 23–30 days
- Fry per Brood: 15–30 (sometimes more, depending on the female’s size and health)
- Breeding Age: As early as 2–3 months
Tips for Successful Breeding
- Keep more females than males to reduce harassment.
- Provide dense plants or spawning mops for fry to hide from adults.
- Feed breeders a high-protein diet to increase fry health.
- If desired, separate pregnant females into a breeding box or separate tank.
Fry grow quickly and can start showing colors within a few weeks. They should be fed powdered flake food, baby brine shrimp, or microworms.
Lifespan
Yellow Tiger Endler Guppies typically live for 2–3 years under good care. A nutrient-rich diet, stable water parameters, and low stress conditions maximize their lifespan.
Tank Mates for Yellow Tiger Endler Guppy
These guppies are excellent community fish and get along with other small, peaceful species.
Compatible Tank Mates
- Neon Tetras
- Ember Tetras
- Harlequin Rasboras
- Corydoras catfish
- Otocinclus
- Cherry shrimp and snails
Tank Mates to Avoid
- Aggressive or fin-nipping fish like tiger barbs or bettas

Common Health Problems
Though generally hardy, Yellow Tiger Endlers can suffer from some common aquarium illnesses:
- Ich (White Spot Disease): Characterized by white dots on the body, caused by parasites
- Fin Rot: Bacterial infection leading to frayed fins, often due to poor water quality
- Velvet Disease: Caused by parasites, giving the fish a dusty gold appearance
- Internal Parasites: Indicated by weight loss despite normal feeding
Preventing these conditions involves maintaining clean water, feeding a balanced diet, and quarantining new fish before adding them to the tank.
