The more "experienced" the fish is, the more fry she will have. I have had younger guppies have only 5 fry in the first batch, as well as older guppies (approx. 10 months to a year old) that have had 100.
She could produce hundreds of babies
Yes, guppies come in many color varieties including red. If there are two male guppies and one female guppy, the female will most likely become too stressed and will die. Always keep more females than males!
1 to 5 to 40
A feeder guppy is a guppy that is sold or going to be fed to a fish. Guppies are commonly used for this because so many are born at one time, and are usually born once a month.
Guppies are livebearers, and can have about 20-50 babies at a time.
If there is a female guppy and a male guppy in a tank you can almost guarantee the female will be gravid ( pregnant ).
The guppy is named after the Rev. J.L. Guppy of Trinidad, an early collector of the species from the late 1800's. Guppies (Poecilia reticulata) are placed in the family as mollies and mosquitofish. The wild, original guppy is native to Central America, as well as Trinidad and northern South America. Today, many guppies are found in Asia, especially Singapore, where many fancy strains are bred in large fish farms, and shipped to pet stores all over the world. The Fancy Guppy Fancy guppies are the result of specialized breeding techniques and they only slightly resemble the small, wild guppy, often seen in pet stores labeled "feeder fish". Guppies are freshwater fish. Their tanks should contain no salt. http://www.TheExoticFish.com
Yes - there is virtually no limit to how many female guppies can live together.
Many male guppies have 'black spots' but if by "black spot" you mean "gravid spot" then no, a male guppy can not be 'gravid' because gravid is the equivalent of "pregnant" and male guppies can not get pregnant.
The Guppy is a single species. There are many variations (varieties) that have been developed by breeders but they are all the same species and can interbreed.
guppies do not lay eggs the give birth to fry(baby guppies) and it depends on the environment it is in.. anywhere to 2-100.Guppies do not lay eggs. They give birth to live swimming young, like dolphins.
Many Fish don't eat guppies, like the neon fish. That is the most common mix I know.
My very small Fantail Guppy had 14 fry and all have survived so far. Approximately 3 weeks.
