Will cory cat's help with brown algae and will they eat my platy fry??

:( no body around here has any. Bummer. Not sure if I want to order or just look for a bristlenose pleco, but I like the albino ones best and I'm guessing no one has those either. GAH I hate the stupid stores around here!
 
...my bristlenoses don't need zucchini blanched - I just add med.thick slices, skewered onto a thin plastic stick and poke it into the substrate...all the bristlers, albino and gray, come swimming. Next morning 80 % is munched up and the peel has a lovely lace pattern chewed in it...
