Fire Endler Guppy – Poecilia wingei

The Fire Endler Guppy (Poecilia wingei) is one of the most fascinating nano fish in modern aquaristics. Intense orange‑red colours, lively behaviour and small size make this variety ideal both for beginner aquarists and experienced collectors of rare livebearers. In this article you will learn how to care for Fire Endlers, how to arrange a beautiful tank, how to breed them and what you should pay attention to before purchase. You will also find out how MB Store, with its wide range of aquariums and aquarium equipment, can help you create perfect conditions for these tiny gems.

Origin and characteristics of the Fire Endler Guppy

Poecilia wingei is closely related to the classic guppy (Poecilia reticulata), but is considered a separate species with its own lines and colour varieties. The Fire Endler is a selectively bred form that emphasises glowing orange, red and sometimes yellow tones, often contrasted with dark edges on the fins and metallic highlights on the body.

In the wild, Endler guppies originate from Venezuela, where they inhabit warm, calm waters rich in vegetation, such as small lagoons, canals and slow streams. These habitats are usually shallow, sunlit and full of algae, aquatic plants and micro‑organisms that form the natural diet of the fish.

The Fire Endler Guppy is characterised by:

• Very small size – males usually 2–2.5 cm, females around 3–4 cm.
• Intense orange‑red body and caudal fin with contrasting patterns.
• Slender build and triangular, often slightly extended dorsal fin.
• High activity – constant swimming, displaying and exploring the tank.
• Peaceful nature and good compatibility with other small species.

These features make Fire Endlers perfect inhabitants of nano aquariums, plant tanks and decorative community tanks. With good care and suitable conditions, they live about 2–3 years, often reproducing regularly during this period.

Aquarium set‑up for Fire Endler Guppies

To enjoy the full beauty of Fire Endlers, it is worth preparing an aquarium that will emphasise their colours and provide them with a sense of security. Although they are small fish, they are very active and curious, so they need enough open space for swimming combined with well‑arranged vegetation and hiding places.

Tank size
For a small group of Fire Endlers, a 30‑litre tank is the practical minimum, but 40–60 litres allows for more stable conditions and a larger, visually impressive group. A long, rectangular aquarium is preferable to a high, narrow one, as it offers more horizontal swimming space.

At MB Store you will find a variety of aquariums suitable for Endlers – from compact nano tanks ideal for desks and small rooms to larger, display‑style tanks for living rooms. When choosing, pay attention to the quality of glass, good silicone joints and a stable stand or cabinet.

Substrate and decor
Fire Endlers look especially attractive against a dark background and dark substrate, which perfectly highlights their fiery colours. Suitable options include fine black gravel, dark sand or specialised plant substrates if you are planning a heavily planted tank.

Decor elements that work well for Fire Endlers:

• Natural roots and branches, providing shelter and creating a natural look.
• Stones forming caves and terraces.
• Leaf litter (e.g. Indian almond leaves) that releases beneficial tannins.
• Coconut shells and small hiding places for fry.

All decorations should be stable and free of sharp edges. When buying decorations and substrate, it is worth looking for products designed specifically for aquariums – available in the MB Store range of aquarium equipment and accessories.

Filtration and aeration
Despite their small size, Fire Endlers require efficient, but gentle filtration. A sponge filter or a small internal or hang‑on‑back filter with adjustable flow will work very well. The goal is to ensure good biological filtration and oxygenation without creating a strong current that would tire the fish.

In nano tanks, sponge filters powered by an air pump are particularly recommended. They are safe for fry, provide a large surface for bacterial colonies and gently circulate the water. MB Store offers various filter types, air pumps and accessories, allowing you to adapt the filtration system to the size and style of your tank.

Lighting
Appropriate lighting not only enhances the colours of Fire Endlers, but also supports the growth of plants. LED lamps with a neutral or slightly warm colour temperature (around 6000–7000 K) are an excellent choice, ensuring vivid colours and low power consumption.

Too strong light without adequate plant mass can increase the risk of algae. It is usually good to start with 6–8 hours of lighting per day and adjust depending on plant growth and the appearance of algae. Using a programmable timer, also available as part of modern aquarium equipment, helps maintain a stable day‑night rhythm.

Water parameters and maintenance

Fire Endler Guppies are considered hardy and adaptable, but stable, suitable water conditions are essential for vibrant colours, good health and successful reproduction. Their natural waters are warm, slightly hard and usually alkaline, but thanks to years of captive breeding, Endlers tolerate a somewhat wider range of values.

Recommended water parameters

• Temperature: 22–27 °C (optimal 24–26 °C).
• pH: 6.8–8.0, with a preference for neutral to slightly alkaline water.
• General hardness (GH): 8–20 dGH.
• Carbonate hardness (KH): 4–12 dKH.
• Ammonia and nitrites (NH3/NH4, NO2): always 0.
• Nitrates (NO3): preferably below 20–30 mg/l.

Heater and temperature stability
Although Fire Endlers can handle slight fluctuations, sudden temperature changes stress them and weaken their immunity. Therefore, a reliable heater with a thermostat is recommended, especially in regions with cool nights and winter seasons. MB Store offers heaters of various power levels, which can be matched to both nano aquariums and larger display tanks.

Regular maintenance
To keep Fire Endlers in top condition, follow a consistent maintenance schedule:

• Weekly water change of 20–30% with dechlorinated, temperature‑matched water.
• Gentle cleaning of the sponge or filter media in aquarium water (never under the tap).
• Removing excess detritus from the substrate with a gravel vacuum.
• Trimming plants and removing decaying leaves.

Frequent large changes in parameters should be avoided; stability is more important than striving for perfect numbers. Using quality water conditioners, bacterial starters and test kits – all found in MB Store’s offer – allows you to control the condition of the water and react in time to any problems.

Acclimating new fish
When introducing Fire Endlers into a new aquarium, it is worth taking time to acclimate them carefully. A drip acclimation method works very well: water from the aquarium is slowly added to the transport bag or container, equalising temperature and chemistry. This helps reduce stress and the risk of shock, especially when parameters differ between the store and your home tank.

Feeding Fire Endler Guppies

Fire Endlers are omnivorous livebearers with a strong preference for small live and frozen foods. Their rapid metabolism and active lifestyle mean they should be fed regularly, but with small portions. Overfeeding quickly leads to water quality problems, especially in smaller aquariums.

Types of food
Fire Endlers accept a wide variety of foods:

• High‑quality dry foods – micro granules, fine flakes, crumble designed for nano fish and livebearers.
• Live foods – newly hatched brine shrimp (Artemia), daphnia, micro‑worms, grindal worms.
• Frozen foods – daphnia, cyclops, finely chopped bloodworms (in moderation).
• Plant‑based supplements – spirulina flakes, blanched spinach or zucchini, green dry foods.

Well‑balanced feeding supports intense colouration, fertility and immunity. Variety is particularly important: alternating dry, live and frozen foods prevents deficiencies and stimulates natural hunting behaviour.

Feeding schedule
Adult Fire Endlers can be fed 1–2 times a day, with only as much food as they will eat within 1–2 minutes. In breeding tanks or for growing fry, 3–4 small meals a day work better. Any uneaten food should be removed to avoid pollution.

MB Store offers a wide selection of complete and specialised fish foods, including products tailored to small livebearers and nano species. When choosing, pay attention to the composition (high content of animal protein and quality plant components) and particle size suitable for the small mouths of Endlers.

Supplements and colour enhancers
Some foods contain natural colour enhancers (e.g. astaxanthin, paprika, spirulina) that support the development of red and orange tones. Used as part of a varied diet, they can further emphasise the fiery colours of your Endlers. It is better to avoid excessive use of strongly artificial colour‑enhancing feeds and instead rely on well‑balanced, natural ingredients and good overall care.

Social behaviour and suitable tankmates

Fire Endler Guppies are extremely social and feel best in groups. Males are constantly busy displaying to each other and to females, showing off their fins and colours. This behaviour is natural and usually harmless, as long as the tank is large enough and there are enough hiding places and plants.

Group composition
To avoid excessive chasing of females, it is recommended to keep Fire Endlers in a group with more females than males. A good rule of thumb is at least 2–3 females per male. For example, a group of 4 males and 10 females works well in a 40–60 litre tank.

If you are interested in preserving colour lines and avoiding uncontrolled crosses, it is important to keep Fire Endlers separate from ordinary guppies (Poecilia reticulata). These species can hybridise easily, and the offspring may lose the characteristic appearance of the Fire line.

Compatible tankmates
Thanks to their peaceful nature, Fire Endlers can be kept with many other small and calm species. Suitable companions include:

• Small tetras (e.g. ember tetra, neon tetra, glowlight tetra).
• Small rasboras (e.g. chili rasbora, harlequin rasbora).
• Peaceful bottom dwellers – Corydoras pygmaeus, otocinclus catfish.
• Small shrimps – Neocaridina and Caridina (though some fry may be eaten).
• Snails – nerites, ramshorns, Malaysian trumpet snails.

It is better to avoid large, aggressive or fin‑nipping fish such as bigger barbs, certain cichlids or bettas with a tendency to attack colourful, active tankmates. Fire Endlers are small and can be easily stressed or injured by more dominant species.

Planting and hiding places
Rich planting is beneficial not only for aesthetics but also for the well‑being of the fish. Plants provide a sense of security, help divide the space into territories and are extremely important if you plan to raise fry. Recommended plants include:

• Fine‑leaved stems – Myriophyllum, Cabomba, Limnophila.
• Floating plants – Salvinia, frogbit, water lettuce, duckweed.
• Mosses – Java moss, Christmas moss, which create excellent nurseries for fry.
• Easy rosette and rhizome plants – Anubias, Cryptocoryne, Java fern.

MB Store offers a wide selection of live and artificial plants, as well as plant care accessories such as fertilisers, CO₂ systems and aquascaping tools. With the right combination of plants, your Fire Endlers will feel comfortable and display their full behaviour repertoire.

Breeding Fire Endler Guppies

One of the greatest attractions of keeping Fire Endler Guppies is how easily they breed in captivity. They are livebearers, which means females give birth to fully formed, free‑swimming fry rather than laying eggs. With good care and suitable conditions, you can observe births every few weeks.

Sexual dimorphism
Males and females differ clearly in appearance:

• Males – smaller, more colourful, with an elongated anal fin transformed into a gonopodium (copulatory organ).
• Females – larger, more rounded, with a fuller belly and less intense colours, usually grey or beige with subtle patterns.

Thanks to this, you can easily plan the composition of the group and select breeding individuals with the most attractive colouration.

Conditions for breeding
Fire Endlers breed willingly in normal community tanks, but to control the lines and ensure better survival of the fry, many aquarists set up separate breeding aquariums. A 20–30 litre tank with sponge filtration, dense plants (especially mosses) and stable parameters is usually sufficient.

Feeding future parents well with live and frozen food increases fertility and fry fitness. Slightly higher temperatures (around 25–26 °C) can speed up the development of embryos, but should not be exaggerated to avoid stress.

Gestation and birth
The gestation period of a Fire Endler female is usually 21–30 days, depending on temperature and individual factors. As birth approaches, the female’s abdomen rounds noticeably, and a dark pregnancy spot near the anal fin may become more visible.

During birth, the female expels one fry at a time. A single litter typically consists of 10–30 fry, though numbers depend on the female’s age and size. It is best not to disturb the fish during this time – avoid sudden light changes, tapping on the glass or intense work in the tank.

Protecting and raising fry
Adult Fire Endlers sometimes eat their fry, especially if there are many fish in the tank and hiding places are scarce. To increase fry survival, you can:

• Keep pregnant females in a separate breeding tank richly planted with mosses and floating plants.
• Provide dense plant thickets in a community tank for fry to hide in.
• Remove adults from the breeding tank shortly after birth.

Fry are tiny but immediately able to swim and eat. At first, they should be fed very fine food:

• Infusoria and liquid fry foods.
• Powdered flakes or micro granules.
• Newly hatched brine shrimp (after a few days).

Frequent small feedings (3–4 times a day) and regular small water changes promote rapid, healthy growth. MB Store provides specialised fry foods and micro‑foods perfectly suited for raising young Endlers.

Health, prevention and common problems

With proper care, Fire Endler Guppies are robust. Many problems encountered by aquarists result from neglected water quality, overcrowding, incorrect nutrition or careless introduction of new fish. Prevention is more effective and less stressful than treatment, both for fish and the aquarist.

Preventive measures

• Regular water testing for ammonia, nitrites, nitrates and pH.
• Quarantining new fish before adding them to the main tank.
• Maintaining stable temperatures and avoiding sudden changes.
• Balanced diet with a variety of food sources.
• Proper stocking level – do not overload the tank.

Many of these tasks are easier with the right tools: test kits, heaters, filters and water treatment additives available in MB Store’s range of aquarium equipment.

Common diseases
Among diseases that may affect Fire Endlers are:

• Ich (white spot disease) – white grains on the body and fins, rubbing against objects.
• Fin rot – fraying fins, often due to poor water quality or bacterial infections.
• Internal parasites – weight loss despite normal or increased appetite.

At the first sign of any abnormality, it is advisable to check the water parameters and, if necessary, isolate the sick fish in a quarantine tank. Only then should you consider targeted treatment using appropriate medications, following the manufacturer’s instructions and observing the reactions of the fish.

Stress reduction
Stress is a major factor behind many illnesses. To minimise it:

• Provide rich planting and hiding places.
• Avoid sudden noises, vibrations and bright flashes of light near the aquarium.
• Do not tap on the glass and limit rapid hand movements during maintenance.
• Keep stocking compatible and avoid aggressive tankmates.

Calm, stable surroundings help Fire Endlers display natural behaviours and maintain immunity, significantly reducing the risk of disease outbreaks in the aquarium.

FAQ – Fire Endler Guppy (Poecilia wingei)

How big of an aquarium do Fire Endler Guppies need?
For a small group of Fire Endlers, a 30‑litre tank can be enough, but 40–60 litres is much better for long‑term care and breeding. A larger volume provides more stable water parameters, more swimming space and better conditions for plants, making maintenance easier and the fish less stressed.

Can Fire Endler Guppies live with normal guppies?
They can coexist peacefully, but they hybridise easily with standard guppies. If you mix them, offspring will often lose the characteristic Fire Endler colours and body shape. If you wish to preserve the pure line and predictable appearance of future generations, it is better to keep them in a separate aquarium.

Do Fire Endler Guppies need a heater and filter?
A filter is essential for biological balance and clear water. A heater is recommended in most homes to keep the temperature stable between 24–26 °C. Sudden drops, especially at night or in winter, weaken immunity. MB Store offers various heaters and filters suitable for both nano and larger tanks.

How often do Fire Endlers reproduce and how many fry do they have?
Females can give birth roughly every 3–4 weeks, depending on temperature and condition. A single litter usually numbers 10–30 fry. In a well‑planted tank, some young will survive even without special care, but if you want to raise more, use a separate breeding tank with dense plants for shelter.

What should I feed Fire Endler Guppies to enhance their colours?
Provide a varied diet: quality dry foods for livebearers, live or frozen brine shrimp, daphnia and small worms. Foods containing natural colour enhancers such as spirulina or astaxanthin support red and orange pigments. Combined with clean water and good lighting, this keeps Fire Endlers intensely coloured and active.
