Guppy Facts

  • Guppies do not lay eggs. As livebearers, guppies give birth to free-swimming baby fry.

  • A female guppy can give birth to fry approximately every 28-35 days.

  • There are many different types of guppies with different colors and shapes.

Guppies are one of the most best-known tropical fish in the aquarium hobby today. While they were introduced to aquarists over a century ago, they remain very popular to this day. Guppies are relatively easy to take care of, making them a great choice for novice aquarists. They are generally very hardy and able to accept a wide range of conditions in an aquarium. While taking care of guppies is not difficult, they appear with many different color forms and tail shapes. The art of breeding different strains of guppies makes them attractive for advanced fishkeepers as well. Once you set eyes on one of these magnificent little fish, it is very easy to understand why they are so popular.

Guppies are named after the English naturalist John Lechmere Guppy. When he brought the fish from Trinidad to England in 1866, the fish was named Girardinus guppii in his honor by Günther, a famous zoologist who was the head of the British Museum at the time. However, guppies were collected by a German zoologist J. L. Peters years earlier in 1859. Peters named the fish Poecilia Reticulata, which takes priority today.

Guppy Care

Guppies are hardy little fish and do not require much special care. While fancy tank setups are not required, basic care and regular maintenance will be necessary. Due to their long fins you must be aware of other aggressive fish that may become fin-nippers. In addition, the nitrogen level must be kept low in order to prevent fin rot. For the same reason, guppies should only be introduced to established aquariums.


Feeding Guppies

Guppies are omnivorous so they will appreciate a varied diet. They are not picky eaters and they can certainly survive one type of flake food alone. However, a varied diet will aid in raising healthy happy guppies. Other than commercial food, live food will be greatly appreciated. In nature, they commonly dwell on mosquito larvae and other small insects. Small amounts of live plants such as duckweed may be beneficial as a part of a balanced diet as well. Guppies should be fed sparingly and often. Feeding once or twice a day as much as they can consume in 2 - 3 minutes is recommended.

Guppy Varieties

The different types of guppies available today are tremendous. Guppies come in various colors, shapes, and sizes. Many categories and classes are present according to their colors and shapes. They are often compared to Nishikigoi in that while they are seen in a number of recognized varieties, their coloration and pattern variations are limitless.
