Harlequin Rasbora Growth Rate?

[CherryNova]

We picked up some more Harlequins for our new tank the other day and a couple that ended up in the bag are so tiny that they are practically still fry. I won't be adding any more fish for a few weeks yet but I do plan on adding Pearl Gourami and 1 (very small) Angel. I want to give the Rasbora time to beef up a little before adding the bigger fish, how quickly do they tend to grow? Any food reccs to give them the best start? Thanks in advance!

Lots of frozen food, brine shrimp, bloodworms or glassworms, live blackworms and a good flake.
