Venus in the Clouds

On Venus in the clouds, the temperature is just right for life. But on Earth we have bacteria that get swept up from the surface and see in our clouds for about a week before they get rained back down. The thought is that because the Venus surface is too hot for life, that life could exist in the clouds where it's much cooler. And that could be life possessing the same kind of chemistry that we have? Well, maybe similar, but definitely not the same.
