Assorted Male Guppy 3.5cm – Poecilia reticulata

The Assorted Male Guppy (Poecilia reticulata) is a colourful freshwater livebearer known for its bright patterns, attractive fins and active personality.

At approximately 3.5cm, these males are already showing good colour, although their pattern and finnage may continue to develop as they mature.

These Guppies are supplied in assorted colours, patterns and tail styles. Individual fish may display combinations of blue, red, orange, yellow, green, black and metallic shades, making each group a little different.

Male Guppies are peaceful, active fish that work well in planted and community aquariums. They can also be kept successfully in male-only groups, providing plenty of colour without the constant breeding that occurs when males and females are housed together.

Assorted Colours & Patterns

One of the most appealing things about assorted male Guppies is the variety between individual fish.

Selective breeding has produced Guppies in a huge range of colours, markings and fin shapes. Individual fish may display combinations of:

• red and orange
• blue and turquoise
• yellow and gold
• black markings
• metallic or iridescent colour
• spots, patches or patterned tails
• different flowing tail shapes

Fish are selected from the colours and patterns available at the time of your order. Product photos should therefore be considered examples rather than a guarantee of the exact colour or pattern you will receive.

Keeping Male Guppies Together

Male Guppies can be kept successfully without females and do not require females for their wellbeing.

Male-only groups are a popular choice for fishkeepers who want plenty of colour and activity without producing fry.

Males may occasionally display, chase or compete with one another. Providing enough aquarium space, plants and visual cover gives individual fish somewhere to move away when needed.

If males and females are kept together, breeding is highly likely. Where both sexes are kept, several females for each male helps reduce persistent attention toward individual females.

Aquarium Setup

Male Guppies are active fish that appreciate a well-filtered aquarium with open swimming areas and plenty of plant cover.

A suitable Guppy aquarium can include:

• live aquarium plants
• floating plants
• open swimming space
• gentle to moderate water movement
• reliable biological filtration
• good oxygenation

Planted aquariums work particularly well for Guppies. Plants provide shelter and visual barriers while their green foliage helps the bright colours of the fish stand out.

Browse our Live Aquarium Plants range if you are setting up a planted Guppy aquarium.

Water Conditions

Guppies are adaptable fish, but they generally do best in moderately hard to hard, neutral to alkaline water.

• Temperature: 22–28°C
• pH: 7.0–8.2
• General Hardness: Approximately 8–20 dGH

Very soft, acidic water is not ideal for long-term Guppy care.

Stable water quality is more important than continually adjusting the aquarium to reach an exact number. Regular water changes, sensible stocking levels and reliable filtration will help keep Guppies healthy.

Tank Mates

Male Guppies are peaceful and can live with many other community fish that prefer similar water conditions.

Possible tank mates include:

• Corydoras
• small peaceful Tetras
• Rasboras
• peaceful Gouramis
• Bristlenose Catfish
• Platies
• Mollies
• other peaceful Guppies and livebearers

Avoid aggressive species and known fin-nippers. The bright colours and flowing tails of male Guppies can make them particularly vulnerable to fish that nip fins.

Feeding Male Guppies

Guppies are omnivorous and straightforward to feed.

A varied diet can include:

• quality tropical flakes
• micro pellets or small granules
• Guppy-specific foods
• spirulina and vegetable-based foods
• frozen brine shrimp
• daphnia
• appropriate small live foods

Feed small portions that can be eaten readily rather than allowing excess food to accumulate in the aquarium.

Male Guppy Identification

Male Guppies are generally smaller and considerably more colourful than females. Selectively bred males often develop larger and more decorative dorsal and tail fins.

Males can also be identified by their gonopodium, the narrow modified anal fin used during reproduction.
