Color-Changing Guppy

Posted by BirdBoy on July 15, 2010 at 6:33 PM Comments comments (1)

Around 2 years ago i bred a guppy that could change its color spontaniously and frequently. I know thats a little hard to believe, but its true. His tail would stay yellow most of the time, but would change to sky blue, red, orange, pink, black, pink with a black stripe down the center,  even with a multi-colored circle in the middle. It was a feeder guppy, but I have no idea where the trait came from.

       He died in my pond, along with the rest of my guppies that could have carried the trait. But I saw some in the San Diego zoo, in the snapping turtle tank. What I really want is to put the word out so the trait can become an established strain. If everyone starts looking for them, this could become possible. Their tails are usually completely yellow, but change color. Just picture adding food color and watching it spread and replace the previous color.

      Also, I need to give them a name. I was thinking of "Spectrum Guppy," but I don't know. Hope people find some guppies.

Fancy guppies (Poecilia reticulata)

The Fancy Guppy, the common livebearers you see in your local fish stores. They are bred for the fancy colors such as Leopard, Red blonde and Purple moscow. And the fancy finnage too such as delta and ribbons. They are much bigger than their wild forms but not as hardy as their wild forms due to they are highly inbred in many generations and are very sensitive to their water quality so their water must be kept as clean. Not the first fish for beginners. Fancy Guppies are very colorful but fragile as they are easy target for nipping fishes such as danios and barbs. The fancy guppies cant handle current very well as their long tails are dragging around. Local bred or home raised fancy guppies are much hardier than imports.

Temp: 76 to 86*F (24-30*C)
Size: 2 1/4 inch long in both sexes.
                *Giant SuperGuppies can reach more than 3inch long*
Diet: Plant matters through they are not fussy eaters as they can take any prepared foods or live foods you can offer to.
Fry Size: Can have up to 100 fry but the average is 60. The parents will eat their fry but not in predatory mode as Mosquitofish and swordtails.
Minimun tank size: 10gal for three trios.
p.h: 5.5 to 8.0

Feeder guppies (Poecilia reticulata)

Feeder Guppy are bred as feeder fishes for the big fish to eat them. Feeder guppies can be fancy guppy culls, mutts, bad broodstock or wild forms. Most feeder guppies you see are wild forms with some fancy traits or none. They are not 100% wild guppies. The feeder guppies are more bigger than Endler's livebearers but smaller than Fancy guppies. The feeder guppies can be attractive as their random patterns and their neon colors are very striking but not striking as Endler's livebearers. Feeder guppies are much hardier than fancy guppies but because of the feeder fish conditions they in, are always heavily diseased. But with some medical, they are very easy fish to take care of, just add water and they will breed.

Temp: 76-86*F
Size: Males 1 inch long, Females 2 1/4 inch long.
Fry size: Can have up to 100 fry but the average is 60.
Diet: Not fussy eaters as you can feed to them anything through they like plant matter.
Minimun tank size: 10gal for three trios.
p.h: 5.5 to 8.0

Other names: Millionfish, Common Guppy, Wild Guppy.

Guppy Tail And Colour Variations

A Guppy? Which Type!

As I am sure that all of us have either kept a guppy or heard of them. A guppy is on of those fish where you can choose what the fry will turn out like by selecting the right parents, this is classed as selective breeding in which i will go into more detail later on. The guppy is part of the millions fish family meaning millions of different colour fin and tail variations as well a the albino.


Guppies come in all colours of the spectrum going from light blue to blood red. There are a variety of colour patterns as a result of selective breeding i which they choose what colours go with what and determine the colour pattern. Because of this varieties and strains are created for example the snake skin guppy (pictured), or a red-tuxedo, there are many more but the list would go on forever.

Snake Skin

Colours are split into two types;ground colour and cover colours. Such as a blond which has a light coloured base or ground colour, and then secondary or cover colour of a light blue and orange. Most Guppies will follow this principle apart from single coloured guppies. All of this can be determined down to precise selective breeding programs.

Tail Variations

As well as having many different colour types and patterns, the guppies tail (cadual fin )
also comes in many shapes and forms again due to generations of selective breeding.
Tail variations are created from breeding a pair of guppies right from the start and then choose the longest finned male and female from that batch and breed them and so on.
This is called creating a strain of guppy.

But guppies don't just come with long tails, they come in many different shapes such as a swordtail, delta tail (pictured), short fin, pin tail, lyre tail an many more.

Delta Tails

Combining The Two

By combining the different tail types and colour variations creates a unique guppy, so it is hard to find a guppy 100% identical right down to the last mm in the tail and the last pigment in the skin. This gives you enough choice to choose a fish that you like.

Obviously with lots of different types of colour and tail varieties there will obviously be guppy shows, where breeders try and breed the guppy with the best colour and tail combinations to create the 'perfect' guppy. It takes a lot of hard work to breed a show quality guppy, this includes many generations of selective breeding and countless fish tanks set up around the house or in a shed full of them, otherwise known as a 'fish house', with such hard work sow quality guppies are not cheap as thy can be £35+ for a single adult or juvenile male guppy, whereas you would find them for £2.50 at your local fish store.

Selective Breeding

Selective breeding is when you choose the colours and tail patterns to your specific requirements, by doing this it takes a lot of breeding. By firstly selecting a pair of guppies that are near to your requirements, you would then choose the best pair from the first batch of fry then breed them. You can do this until you get the perfect guppy. This is then 'selecting' the parents and then 'breeding' them to create the fry to your taste or the judging board in show cases.

In Summary

If your looking for a bright colourful fish with many different types of colours and tail shapes and being able to breed many different patterned guppies, and because they are so easy to breed anyone can, but it is not easy to create strains of guppies as it takes a lot of selective breeding. Or you can just have fun and breed them for the excitement of breeding and caring for your own little baby fish.
