Platy Growth Rate?

I have 10 platy fry and i am just wondering what is the platy growth rate, please could you give me links or knowledge of how long it will take for the platy to grow full size?
Could you tell me the growth of the platies through different stages of age?
Thanks Danny
P.s Best answer 10 points!!
Answers:
I've raised platies and other livebearers for about 30 years. They will be large enough to be with other fish and not eaten within 3-5 weeks. Depends on the water conditions and the food. Feed them well with high quality foods, provide them with a clean healthy environment, the will grow faster and larger.

I am not a big specialist of that question but believe:
- adult size around 1 - 1.5inch
- size + colours should be reached at around 8 weeks old
I hope that helps

normally fishes grow their whole life.
platies are sexually mature when they are three months old, but they are still rather small at this point (3 cm, that is 1.18 inches). they achieve their "normal" size, that is about 5 cm (2 inches) for males and 6 cm (2.36 inches) for females at the age of 5-6 months depending on the water temperature and amount of food they can get.
slightly higher temperatures boost the fish metabolism and fishes age faster because of that.
lack of food in the infancy leads to smaller sizes in the adulthood, this is true for all vertebrates.
be aware though, that there are many hybrids between platys and swordtails. the hybrids are generally larger than platies. they will achieve the size of standard platies at 4 months already and looking a bit shorter but higher and wider than swordtails in the age of 6 months.
Once swords, mollies and platies are about 3 to 4 months old the males become quite evident by their pointed anal fins. They become sexually mature at 3 to 6 months. They grow at different rates so growth and maturity is very dependent upon water conditions, feeding, water temperature, population of the tank, genetics, future adult size, etc, so there really isn't a specific 'growth rate' estimation I can give you. Even if you gave me all the information about all these factors I just couldn't do it. You will just have to watch them and determine their sex when they are ready to, um, "show you". ;-)
