I'll bet they can sting after ingestion. Cut one in half. The business end can still bite. Yeah, I just had to try it. However, like you, I doubt that enough hit the water to be a serious problem. What I don't know is whether the bite can really harm a fish. I guess an aquarium test would tell the answer. Texas is loaded with fire ants. I have them but rarely see a dead fish. And, with the exception of a flood, I never see them in the water.
