The only problem I think u will have in putting her in with ur platty fry is, her eating some of them...My fish never stop eating. what I done is, I have a seperate tank for nothing but having fry...I call that my marternity tank...after she has all her fry, I put her back in the guppy or molly tank. then I remove those and put them in the fry tank... I know people say that with fry u have to be careful with what u do to them...But I have found that fry is alot more tolerant than what u may think. I hope maybe I helped alittle. Good luck
