Fish with juvenile bullfrogs?

Now, recently, I've been finding a few drowned crickets in my tank, some of which I don't exactly want to grab, and of course, lots of bio-waste, though almost all of it is sucked up by the filter. But the filter doesn't reach some parts of the tank, so I was wondering: Could I keep fish or small shrimp in my tank with the juvenile bullfrogs? Perhaps a few feeder goldfish? Gnag is big enough to eat some, so she might go for 'em, which could be a bit of a treat for her. Or some Rosy Red Minnows? My friend [The one who will adopt Bumpy when she is too big, and is getting the 3 Green Tree frogs as you can see in this post: http://www.frogforum.net/tree-frogs/...re-sheet.html] is breeding them for his captive Black Crappie [As food]. But I need something that would either eat drowned crickets, or clean up after the frogs, the first of which would be better. If possible, a fish that looks similar to a trout, salmon, or Black crappie? I'd rather keep the size down to under 2 1/2 inches long. So, any suggestions? I need to know before tomorrow, because that's when I'm picking up the fish.
