Black Fire Endler Guppy Pair (Poecilia wingei)

Black Fire Endler Guppy Pair (Poecilia wingei) is a male-and-female livebearer pair selected for compact size, active behaviour and a dark orange-to-black ornamental pattern. The male carries most of the display colour, while the female is larger and more subdued. This listing is explicitly a pair, unlike the many unsexed or single-fish livebearer products in the catalogue.

Quick care

Aquarium setup

Use a mature planted aquarium with gentle filtration, open swimming space and dense cover around the edges. A sponge filter or protected intake is useful if you want fry to survive. Moss, guppy grass, hornwort and floating plants provide shelter and grazing surfaces.

Forty litres can house a pair, but 50–60 litres or more is much easier once fry appear or if additional livebearers are present. Stable water volume also reduces sudden changes in temperature and waste concentration.

Water parameters

Endlers generally suit the mineral-rich water found in many UK areas. Keep the aquarium around 22–28°C, with pH 6.8–8.5 and moderate-to-hard water. A stable 24–26°C is a useful daily target for a normal indoor aquarium.

Ammonia and nitrite must remain at zero. Keep nitrate controlled with regular partial water changes. If your source water is very soft, test GH/KH before adding minerals rather than making assumptions from postcode or tap-water taste.

Feeding

Use a good-quality fine flake or micro-pellet as the staple. Rotate small frozen or live foods such as daphnia, Artemia and cyclops, and include some plant/algal content in the wider diet. Adults also graze biofilm and fine algae between meals.

Feed tiny portions once or twice daily. Endlers appear hungry almost constantly, so portion by what they can clear quickly rather than by begging behaviour.

Behaviour and sex ratio

Males are active courtship fish and may repeatedly follow a female. A single pair can work where the female has dense cover, but in a larger aquarium many keepers prefer additional females so male attention is spread. If the female is continually hiding, losing weight or being prevented from feeding, increase cover or change the social arrangement.

Do not house this pair with large predators or persistent fin-nippers. Peaceful hard-water community fish of similar size can work, but very soft-water specialists are a poor chemistry match.

Breeding and fry

Endlers are livebearers. Females release fully formed fry rather than laying eggs. In a mature planted aquarium, fry can appear regularly once the pair is settled. Adults may eat some young, so dense moss, floating roots and fine-leaved plants improve survival.

Feed fry powdered flake, microworm-sized live foods or newly hatched Artemia where appropriate. As young males colour up, separate or rehome surplus fish before the aquarium becomes overcrowded.

Keeping the Black Fire line

Poecilia wingei can hybridise with fancy guppies and other Endler lines. If maintaining the Black Fire pattern matters, keep the pair and their descendants separate from other Poecilia strains. Mixed communities are possible, but future offspring may not retain the original pattern consistently.

Health and acclimation

Healthy Endlers are alert, active and feeding, with open fins and steady respiration. Fin deterioration, white spots, weight loss or repeated surface gasping require water testing and a health check rather than automatic medication.

Quarantine new livebearers where possible. Match temperature and water hardness carefully during acclimation, especially when the source and destination water differ significantly.

Before ordering

This pair suits keepers who want a small, active, breeding livebearer for a planted aquarium. Plan ahead for fry rather than assuming the aquarium will remain at two fish.
