Things that go bump against your boat in the night

One night in Man Jack Cay, we heard a loud thump against our boat. We took out the high-powered flashlight to see what it was and there were thousands of these minnows and crabs teeming in the water. The crabs were trying to eat the fish, despite being smaller in size. We scooped up a bucketful of water so that Mark and Conrad could see them in the morning. We think the thump may have been a larger fish trying to eat the smaller ones and jumping against the boat.
