fish food, fish, and 2yr olds-help/advise please

Hi,

I just finished giving my fish tank a 50% water change after finding
out that my 2yr daughter decided that she needed to feed the fish
the remains of an old container of fish food (about 3.5 g of brine
shrimp).

I've skimmed as much off of the fish food off of the top of the
water that I could, and I've set the filter on high to clear the
water out faster. They obvously won't be fed again tonight, and
tomorrow is their scheduled fast day. I'm also thinking of not
feeding them on Thursday, just to be sure, though I don't know if
that's necessary to go that far.

The fish in my tank are comprised of 6 white mountain cloud minnows,
and 3 albino corys.

Aside from keeping an eye on them, is there anything else that I
could, or even should be doing? I'd appreciate any advice that
anyone has to offer.

Thankc in advance,
