Guppy Tuxedo

Guppy Tuxedo is a selectively bred form of Poecilia reticulata, distinguished by its characteristic contrasting coloration: the front part of the body is usually light, while the rear half and tail stem are dark and saturated. The fins may be coloured in various shades, including red, yellow, or blue. Males reach 3–4 cm in length, have more vibrant colouration and pronounced fins. Females are larger, growing to 6 cm, with more modest colouration and a rounded belly.

In nature, Poecilia reticulata inhabits fresh and brackish waters of South America, including Venezuela, Guyana, northern Brazil, and the islands of Trinidad and Tobago. The Tuxedo variety is a result of selective breeding and does not occur in the wild. In aquarium conditions, the fish adapt to a wide range of water parameters, preferring a stable environment with moderate water flow.

These are peaceful and active fish that prefer to stay in the upper and middle water layers. They are schooling fish, so they should be kept in groups of 5–6 individuals or more. They get along well with other peaceful species of similar size. In a community tank, avoid aggressive tank mates that may damage their long fins.

Among aquarium fish, guppies stand out for their hardiness and ease of care. Even a small group needs a tank of at least 40 litres: this volume (45 × 30 × 30 cm) is recommended for guppies. The basic equipment required is modest. A simple air-lift filter and a light source are sufficient to keep them. If you plan to add other tropical fish, provide an additional heater. If both males and females are present, fry will almost certainly appear. Since parental instinct is weak in guppies, provide plenty of hiding places for the young to escape from adults. Dense plantings of fine-leaved plants work well as shelters. The rest of the tank setup is up to you. As for feeding, guppies readily accept most popular foods—dry, frozen, and live—as long as they fit in the mouth. Many manufacturers offer special foods for this group, so finding a suitable product is easy. Guppy Tuxedo are active and peaceful fish, coexisting well with their own kind. However, remember that keeping different varieties together may result in hybrid offspring. They are compatible with many other non-aggressive species of similar size.

The fish are omnivorous. In the aquarium they accept quality dry foods in flake or pellet form, as well as frozen and live foods such as daphnia, brine shrimp, or bloodworm. To maintain colour brightness and health, vary the diet. Feed in small portions once or twice a day; the fish should finish the food in a couple of minutes.

Guppies are livebearers. Breeding occurs easily, often without the aquarist's involvement. The female's gestation lasts about 21–40 days depending on water temperature. A single female can produce between 1 and 200 fry. To preserve the brood in a community tank, use dense plant growth where fry can hide from adults.

The species has a strong immune system but is sensitive to sudden changes in water parameters and poor water quality. Poor care can lead to diseases such as fin rot or ich. Prevention includes regular water changes, keeping the substrate clean, and avoiding overstocking.

When buying, choose active fish with clean scales and undamaged fins. Inspect them for the absence of white spots, ulcers, or unnatural coating on the body. Healthy guppies are curious, have a good appetite, and do not linger at the surface trying to gulp air if the aquarium has sufficient oxygen.
