Pink Tuxedo Guppy Care Guide - Aquarium Tips, Diet & Breeding

Pink Tuxedo Guppies are an ornamental form of the familiar guppy, developed for their rosy pink colouration and contrasting tuxedo-style dark pattern across the rear half of the body. Males are especially eye-catching, with flowing tails and richly patterned fins that can vary considerably between individuals and breeding lines.

These active livebearers spend much of their time in the middle and upper levels of the aquarium. They are generally peaceful, inquisitive and constantly on the move, with males displaying to females and to one another without usually causing serious injury.

In the wild, guppies inhabit shallow, slow-moving freshwater habitats such as streams, pools, drainage channels and vegetated margins. Their adaptable nature has allowed them to live in a wide range of conditions, although selectively bred fancy guppies are often less robust than wild-type fish.

Pink Tuxedo Guppies are livebearers, meaning females retain fertilised eggs inside their bodies and give birth to fully formed, free-swimming fry. They reproduce readily in a community aquarium, making them a popular choice for aquarists who want to observe natural breeding behaviour.

The Pink Tuxedo Guppy is a selectively bred colour and pattern form of Poecilia reticulata, rather than a distinct wild population. Guppies originate from northern South America, including Venezuela, Guyana, Suriname and parts of Brazil, and have since become established in tropical waters worldwide through human introduction.

Allow at least 40 litres for a small group, with a tank measuring approximately 60 cm long by 30 cm wide or larger; a bigger aquarium is preferable because guppies breed freely. Use gentle to moderate filtration with protected intakes, open swimming space and dense plants around the sides and rear, including floating plants for cover. A fine gravel or sand substrate is suitable, while smooth decor, wood and rocks can provide structure without damaging long fins. Keep the aquarium securely covered, as guppies may jump.

Males reach about 3.5 cm (1.4 inches), while females can grow to around 6 cm (2.4 inches).

Offer a varied omnivorous diet based on a quality tropical flake or small granule food, supplemented with spirulina, blanched vegetables and occasional frozen or live foods such as baby brine shrimp, daphnia and mosquito larvae. Their small mouths benefit from several small meals rather than one large feeding. Remove uneaten food promptly, particularly in tanks containing fry.

Pink Tuxedo Guppies suit peaceful community aquariums with small tetras, rasboras, peaceful Corydoras, kuhli loaches, Otocinclus and other calm livebearers. Avoid fin-nipping species such as tiger barbs, aggressive or very boisterous fish, and large predators that may eat them or harass their flowing fins. Males can be kept with females, but a ratio of one male to at least two or three females helps spread courtship attention. Do not rely on guppies being safe with shrimp fry, as adult guppies will readily eat very small young.

Pink Tuxedo Guppies are easy to breed and will usually reproduce without special conditioning. Keep one male with two or three females to reduce persistent courtship pressure. Females give birth to free-swimming young after roughly 21–30 days, depending on temperature. Dense plants such as Java moss, guppy grass or floating cover provide refuge for fry, although a separate breeding or grow-out tank gives more young a chance of survival. Feed fry crushed flakes or a quality powdered fry food several times daily, with newly hatched brine shrimp helping them grow quickly.

Females are noticeably larger and deeper-bodied, with a rounded abdomen and a dark gravid spot near the anal fin. Males are smaller, more slender and more vividly coloured, with a modified anal fin called a gonopodium and typically longer, more elaborate tail and dorsal fins.
