Guppy
Poecilia reticulata
The guppy is a small, very colourful livebearer, ideal for beginning in the hobby. Males display spectacular fins with varied patterns, the result of decades of selective breeding. Hardy and active, it breeds very easily in captivity.

Environment
A tank of at least 54 litres suits a small group, ideally with more females than males to spread out the attention (at least 2 to 3 females per male). The guppy likes rather hard, alkaline water (pH 7 to 8, high GH), between 22 and 28 °C. Dense planting offers hiding places for the fry and softens the light.
Feeding
An opportunistic omnivore, it accepts flakes, pellets and small live or frozen prey. Add a plant component (spirulina flakes) to balance its diet. Small frequent feedings are better than a single large meal.
Tips & tankmates
The guppy is prolific: a single pair can quickly overpopulate the aquarium, so plan for managing the fry. Each female can have around twenty fry every 21 days. Avoid fin-nipping tankmates such as certain barbs. Water that is too acidic harms its longevity.
