Red Dragon Guppy Care Guide - Aquarium Setup, Diet & Breeding

Red Dragon Guppies are a selectively bred variety of the familiar fancy guppy, prized for their intense red colouration and intricate scale patterning. Depending on the line, the red pigment may extend across the body, tail and dorsal fin, while males often display especially dramatic colour and flowing finnage.

Like other guppies, they are active, alert and generally peaceful fish that spend much of their time in the middle and upper levels of the aquarium. They are livebearers, and females can store sperm, allowing them to produce several broods after a single mating.

Wild guppies inhabit a wide range of shallow freshwater environments, including slow-moving streams, pools, ditches and margins of larger waterways. Their natural habitats often contain vegetation, leaf litter and varied shelter, and the species has adapted to conditions ranging from soft forest waters to mineral-rich streams.

The Red Dragon strain is the result of selective breeding in the aquarium hobby, so exact colour intensity, fin shape and pattern vary between breeders. Its bright appearance and lively personality have made it one of the most recognisable varieties of ornamental guppy.

The domestic guppy, Poecilia reticulata, descends from wild populations in northern South America, including parts of Venezuela, Guyana and Brazil, as well as nearby islands such as Trinidad. Red Dragon is a selectively bred aquarium colour and pattern strain rather than a distinct wild species.

A small group of Red Dragon Guppies should have at least a 40-litre aquarium, with a larger tank preferable for a mixed-sex colony or when raising young. A tank around 60 cm long gives them useful swimming space and makes it easier to maintain stable water quality. Use a gentle filter, open swimming areas, hardy plants and some fine-leaved cover for fry, together with smooth gravel or sand and a secure lid, as guppies may jump. Moderate water movement and clean, well-oxygenated water suit them well.

Males usually reach about 3 cm (1.2 in), while females can grow to around 6 cm (2.4 in). Females are therefore roughly twice the body length of males, although fancy strains can vary in overall size and fin length.

Red Dragon Guppies are omnivores and thrive on a varied diet of quality small flake or micro-pellets supplemented with frozen or live foods such as baby brine shrimp, daphnia and mosquito larvae. They also graze on algae and soft plant matter, so occasional spirulina-based foods or blanched vegetables are useful additions. Feed small portions once or twice daily, offering only what they consume promptly.

Red Dragon Guppies can share an aquarium with other peaceful, similarly sized community fish such as platies, mollies, small rasboras, neon tetras, peaceful corydoras and otocinclus. Avoid large predatory fish, fin-nippers and boisterous species that may harass them or damage their flowing fins. Male guppies can continually pursue females, so mixed groups should contain several females for each male; an all-male group is another option if breeding is not wanted.

Red Dragon Guppies are prolific livebearers and usually breed readily in a mature aquarium. Keep a ratio of at least two or three females per male to reduce persistent courtship, and provide dense plants or a separate breeding area where fry can seek shelter. Females give birth to around 20–60 free-swimming fry after a gestation period of roughly 21–30 days, although brood size varies with the female’s age and condition. The adults may eat the newborns, so raise fry separately or provide abundant cover and feed them finely powdered or newly hatched foods.

Red Dragon Guppy males are smaller and more vividly coloured, with a modified anal fin called a gonopodium and often a larger, more elaborate tail. Females are larger-bodied, typically less intensely coloured and have a rounded abdomen; a dark gravid spot may become visible near the anal area when carrying developing young.
