Really depends on what you mean by "Grow up." My Red Wag Platies are at least 6 months old, if not 8 months. They (with regular feedings and water changes) are only HALF the size of the adult platies at the pet store. I would give it a year, at least, before they reach adult size. BUT, be aware! They are able to breed at 10-12 weeks old!thanks! how long does it take for them to "grow up"? i accidentally fell into the fry, so i really don't know anything about them.
