How Long Until Full Grown?

[chibi]

I have guppy fry that's about 3 months old, and they're all about .5" to .75" long. How long until they're full grown? I had them in a breeder net for about a month, but now they've settled in a 6 gallon. I went away for a week and noticed they grew, so they aren't stunted or done growing, but I'd like to know how long until they're full size. Anyone have an estimate?

I had new borns on the 10th of March and they are approx .50" long currently. I just had some drop today and they're about 5mm (0.20") at best. So the growth in a week has led me to an estimate that they'll be ready to be released into the main tank in another 2 weeks at most. I wouldn't know what to class as full size though.
So I don't know what to say about your 3 months, but the old saying of "they'll grow to their surroundings" may be the case.

Under ideal conditions guppies should be pretty close to full size within 4 months. If the conditions are average it will take 6-9 months and in poor conditions they might not reach full size in a year.

The fish you buy from the shops and are bred in Asia are only 3-6months old. 6months for the really big males and about 3months for the smaller ones.

Yes,
they do seem to reach full size in about 6 months but if fed the best food and kept in the best conditions they can reach full size in around 4-5 months.

Mine arrived between the 1st and 7th March. I reckon ther about .7-1" now. They get food 3 times a day, 9am, 3pm, 9pm. First feed Cyclops, second micro worm third cyclops/flake.

They have 12" X 15" X !5" ish in space.... Still cant sex them though >.>

Well i say i cant, i can see 1 male.... If all the rest were female..... 1/28! Happy male guppy lol

Yeah Cooper, I had the same thing almost. 3 males, 12 females. Wonder why...

For Cooper2085

try adding prawn and fish to their diet. Just cut it up into small pieces and offer them a few bits at a time. And do daily water changes.
