     Does anyone know of a vital stain for paramecium?
We're trying to image the movements of paramecium and
want a stain that will provide either intense color or
high contrast, so as to be easily visible in video frames.
Longer term (several hours or longer) toxicity to the paramecium
is not of any concern, but we would like them to be able to
continue swimming for at least an hour or two,
before going flagella-up.
