- Origin: Caribbean islands, and nearby South America
- Size: 6cm /2.5 inches
- Temperature: 17-28°C/ 65-78°F Warmer temps will shorten their lifespan considerably.
- Diet: Guppies in nature are avid mosquito eaters. In your home, they will eat any food you put in the tank.
Guppies belong to the family (Poecilia reticulata). I had started to write about a different fish, but then I realized that this would be my 150th species profile.
So I decided that I should pick a fish that was more important and widespread in the hobby. No fish is more extensive than the common Guppy.
It is a staple in any and every fish store in the world and is probably among every fishkeeper first fish.
Guppies were undoubtedly among the fish in the first community tank that my father set up sometime in 1969. From that time until about 1993, the descendants of those same guppies continued to thrive in that same old metal rimmed aquarium.
Of course, new blood and fresh genes were periodically introduced.
No special techniques were employed to save the young.
No breeding traps or nets.
The only thing:
That protected the infant guppies from the hungry mouths of gouramis, angels, barbs and whatever other fish that caught our fancy over the years was a continuous layer of hornwort that grew at the top of the tank.
Guppies are available in every imaginable color and are sold under a wide range of prices. The inexpensive ‘wild-type’ guppies are sometimes quite attractive, but they are not from the wild.
They are merely guppies that have been crossed over generations with different color forms and tail sizes resulting in unstable color palettes. Many people confuse these short-tailed ‘wild-types with Endler’s Livebearers, but that is a different species of Poecilia that I will cover later.
Breeding a strain of guppies with consistent, stable color is quite hard and requires a lot of room, dedication, and patience. When buying guppies, always look at the tank they are housed in carefully.
If you see anything in the tank swimming or resting with their fins clamped shut, or with sunken stomachs, do not buy anything from that tank!
Genetic inbreeding have made guppies very susceptible to a guppy wasting disease that is very contagious.
You can house a small group of guppies in as little as 8 liters/ 2 gallons of water. In nature, they can be found in tiny puddles with just 2cm (an inch) of water.
They will be happier and more comfortable to keep in larger tanks. The substrate is unimportant, but they prefer to have a lit of plants, floating plants, and water that is not moving.
They prefer hard water to be soft and can be kept in brackish water.
Do not keep with known fin-nippers like Tiger Barbs if your guppies have flowing fins.
Guppies are known as livebearers, but they are not giving birth the same way mammals do.
Eggs develop within the body cavity of the female but receive no nutrition from the mother.
A female can have between 5 and 100 babies every four to 6 weeks. A female can have up to 3 batches of young from a single encounter with a male..and if there are males in their tank, they will always be ‘pregnant.’ Professional breeders divide the females from the males when they are about three weeks old.
This allows the females to grow bigger and prevents unwanted pairings.
