I came home from work today, and my brother tells me, "don't feed your fish for a few days..maybe even a week" WHAT?! he then pursues to tell me that a bratty kid who was there visiting with his mother..who wasn't watching the heathen!!, he dumped a WHOLE bottle of fish food (betta food) into my tropical aquarium!! 
it contains angelfish, cory cats, tetras, fancy guppies, swordtails..etc...it is a 55 gallon aquarium.....
I noticed that ALL Of my fishes bellies are swollen and full! They "scooped" out the food the best they could, what they didn't get, I THINK my filter did a pretty good job of cleaning out! but....there is still quite a bit in my gravel (should I use my gravel vaccum on it?)
and most importantly, should I be concerned about my fish? I don't want them sick!! 
Please help me!!
